Singingly, there are many of you who think about choosing movie programming for Vivchennia, many times I have felt the idea that Java The programs generate higher wages than other programs, as there is virtually no competition.
So anyway, I’m going to try to confirm this fact. I’ll start from the fact that I’m not going to bet the simple connections on the power supply again. To praise such an important decision, and chi varto vichat Java programming language, let us supply ourselves with a number of logical sources, based on them and based on this analysis, we can make detailed conclusions.
What is the metamorphosis of Java programming?
What purpose is needed? The goal is the main motivator, you must learn what you need to achieve. And if the meta is defined incorrectly, then you will collapse in the wrong direction and will not achieve the result you promised.
Kintseva meta learn language Java - otrimat robot.
You learn the programming so that you can then exchange your knowledge for pennies, otherwise you cannot. If you wanted to start writing one single program, then forget about it, because only after going through all the stages of a basic developer, you can sell your ideas, which will then be sold y requested by other people.
That’s the goal, now let’s move on to the features of the business. It’s really not necessary to rush from one task of learning to another, be it Youtube channels or author's blogs that they practice Java navchannya.
In short, you will listen to material specially written as a promotional video for short lessons to a paid course by its author, but to continue hearing, you still need to buy access. You are wondering about the upcoming harmless lessons, and then another author begins the basics again Java programming.
And in the worst case, you will find lessons in writing “unknowingly” or monotonously reading texts that make money on advertising “woe for video bloggers.” You walk around the stake, spend an hour, and after spending an hour you become interested. I tell you that for this very reason, from all the beginnings of programming for materials found on the Internet, only 5% will reach the finish line.
Why don't 95% of corn grow to the finish line?
Vikorist unstructured material
The initial articles, lessons or videos, cluttered together from various authors, do not and cannot have a logically connected structure - it’s just a “mixed porridge”, the axis of such a look will be lost in your head. Write down Basic course in Java For several dozen years, a well-thought-out structure for presenting the material has been of great benefit. Who wants to work without costs?
Irregular navchannya process
If you do not exercise regularly, all your efforts will not bring results. Begin programming as soon as possible or every other day, knowing that you paid pennies for the initial course will keep you energized and motivated to go further. If, by chance, there is no harm, demotivation and performance against you, there is no value in it.
Pochatkivtsi commemorations
Obsession with theory
Trying to master programming theoretically leads to the point where everything has become clear in theory, but in practice it’s a total loss. I first need to write the code, and then close the theory.
Perfectionism
Students often start practicing perfectionism. What's the problem? Having cast off the legacy, one is tempted to retire immediately ideally. This is a priori impossible; the newcomer has no such reassurance. If the task is valid, we set it as meta so that our code can be processed. At the other end of the stage, the code is already optimized.
Why is it a waste if you really want to achieve your goals optimally? You wonder at the task and don’t know what to do ideally and, as a result, waste a lot of time. As a result, nothing will be accomplished, and the task will remain untouched.
Visnovki
There is no need to go far in search of revelations. On any freelance exchange, you will not get dozens of testimonials from applicants who create projects from assignments for Java programmers, based on the number of responses to assignments for PHP programmers. Competition is clearly less, which means less income Java programmer more
And it’s not surprising Java more important language programming And start reading what you need right away with premium video courses. If you are a total newbie, feel free to check out my new video course.
Osvita is not guilty of being a sacred cow, we sing! This is required and can be changed. This is how we did it ourselves and developed a JavaRush programming course, which is not similar to any other online course. There are no long video lectures and a list of instructions, which is unsurprisingly who and how we can verify. Natomism is a clearly defined goal, with the division of special methods for starting and establishing the results that need to be achieved.
Top 12 features of JavaRush lessons
Get online courses with programming, tutorials or video lessons. Everything is wrong with us. We formulated a series of short lessons in Java, filled them with practical tasks and gave them “smart” tools to check the correctness of a solution. And everything seems to follow a consistent and consistent course!Upgrading you as a programmer. These are not just Java lessons for beginners - they are an opportunity to consolidate knowledge in practice “here and now.” You give short lectures, then there you decide the task and take care of this wine city. It’s quite logical and understandable. The task you see is highly tempting. The most extensive task is writing code for the most common problem. Apart from them, you will need to read someone else’s code, correct it, improve it (refactoring), add new features. For those who wake up long enough, expect great things, and mine-projects: when you finish them, you will write a number of serious programs (small games, online chat, and so on).
2. Java lessons, nothing fancy!
Java, even if it is a different programming, can be used for a long time. In order not to bury ourselves in the dense network at the very beginning of the road, we learned from the course that beginners needless to know what programming lessons are often called for. JavaRush has lost only the most useful things. And these are not empty words: this is the result of the analysis of hundreds of vacancies. However, we firmly believe that the course includes the very same things that a new Java Junior Developer will need to know in order to get the hang of it. The process of completing the Java Junior loan will take you three months to one day depending on how many hours you start studying. You will need to read this at any time of the day or night: dark and dark themes are available on the site - choose whatever you want.Light JavaRush theme
Go to the “bright side” (whatever you want, clearly!). All people are different. I feel comfortable writing light text on dark text, but I don’t like it. We have been inspired by our loyalists, and now you can switch to a light theme (“light background, dark text”) in any section of JavaRush!

3. 500 mini-lectures and 1200 + practical assignments.
This course has a lot of practice. So much more practice! The course consists of 500 mini-lectures (short lessons in Java) and more than 1200 practical tasks. Most important things have small ones, or “thousands of them!” If you ignore them, you are missing out on the minimal evidence you need to get your head around the big problems. In addition, we are aware of the so-called great task (essentially, not just projects) and valuable videos.4. Lots of quests, forty levels, tons of practical knowledge.
The course is divided into 4 quests, leather quest – there are 10 levels that need to be completed. The first quest is to learn the basics of Java from scratch, the syntax of the language and the basics on this topic. The middle task is very simple, to master the material covered, but the task is more complex, and for the best ones you will have to get ahead and Google it. This is a special folding arrangement for those who are the most funny. You can “share” for the upcoming market only for the sake of the majority of the production line. If any of them are not suitable, they can be safely put aside for later. In this way, if you reach the end, you will have taken away about 500 years of practical programming. Such a solid application for a successful Java Junior robot!| JavaSyntax quest | For the cobs. In this quest, lessons in Java will help you learn the basic constructions of the language (changeable, smart operators, loops, methods, classes, basic information about collections and objects) |
| Java Core Quest | In this quest you will learn the basics of ORP, become familiar with the serialization and re-invention of methods |
| Java Multithreading Quest | Rich flow is the name of the game for this quest. But here the language is not only about her, but also about the control of the Object and String classes and much more. This quest, as well as the upcoming one, can be completed in one hour. |
| Quest Collections | Collections for a Java programmer are the same as dynamite for a prospector. You need to know them, but you must carefully understand how to profit from them. This quest also has a lot of information about working with JSON, Git, RMI, DynamicProxy and a little about JavaScript |
5. Online internship and preparation before interviews
Beginning with the 35th edition of JavaRush, and even better - after the 40th, students can undergo a special online internship, during which they will study basic Java lessons on advanced technologies and develop a serious project that can be added to their resume. And at this stage, closer to the end of the process, our fakhivs will help you with your resume. There is also a need for various statistics from practice and success stories for those who already know the work. These guys often write great materials for us and are willing to share their distant and recent knowledge with other students.6. The show is there, right there.
You can check the data and send them for verification:- directly on the site. JavaRush is not just Java lessons for beginners. This is another interactive medium for a more successful task. Manually: you know the lesson of the lecture, and now you need to finish a similar task. Such additional information on the attached material can be downloaded directly from the JavaRush website: for which we developed the WebIDE tool;
- For more advanced tasks that require more time, we recommend using a professional tool for developing IntelliJ IDEA. To make it easier for JavaRush students, we created a functional plugin for this popular IDE. The plugin allows you to remove the mental data in one click and it’s that simple and you can quickly submit your decision for revision;
- After you are required to verify the code, the code you enter will be synchronized as you work from different computers/tablets.
7. Mitt's review of the solution.
Students are not too familiar with the situation: the assignment is ready, but the teacher cannot be trusted. Do this yourself in full-time courses, where one student, who teaches Java programming lessons from scratch, deals with two dozen students at once (or even more) and you just need to check the instructions of each of them. On JavaRush you will learn about the correctness/compliance of the meeting's solution. In and:- write solutions in Java;
- Click on the “re-verify” button: your decision is sent to the JavaRush server!
- second - and you will receive information about the correctness of your decision and recommendations for each payment.
9. Help page.
If the JavaRush recommendation system did not help you and you got stuck in trying out some of the most complex tasks, take a look at the help page - on which service you will not be left with a problem. All the students and JavaRush teams will definitely help you.10. Groups based on interests and places.
Collaboration - interest groups, where you can read articles from other students and teachers of Galuzia, write blog topics, take part in competitions, comment and discuss Java and software related topics.11. Social media and JavaRush
Subscribe to JavaRush groups on VK and Facebook. They can discuss IT news, Java programming lessons, share their experiences with friends, watch Java video lessons or ask for help. VKontakte:Vitannya. If you read a lot of series, I confirm that these are Java lessons. The course is simply filled with practice (1200+ practical tasks) and insurance coverage for an adult audience. I hate boring lectures, so JavaRush is spoiled by watching online games (quests).
Have you ever played or upgraded your characters? Sometimes you don’t notice how you get involved, right? Can you guess where I'm going? With JavaRush you may also have the opportunity to upgrade your character. From the 1st level to the 40th. If you complete the entire course, you will become a cool Java programmer.
If you complete 40 levels, you will be able to master Java Java Junior. I want individuals who already found a job on the 20th century. Because there are a lot of practical things in JavaRush. Quite a lot.
These things are burning in the distant, distant future, in the 3017th century, when people will live on Earth with robots, and perhaps the price of space will increase.
Once upon a time, a spaceship crashed on an unknown planet.
Prehistory
The Galactic Rush team has detected accidents on an unknown planet. When the ship fell, it crashed into a mountain and there were rocks all over the place. Several days passed on the Marn and tried to free the ship. The crew, having lost all hope of returning home and starting to settle into their new place.
A week later, Ellie, the ship's navigator, quickly revealed that the planet is inhabited by... thousands of wild robots! The stench could have helped to remove the stones and free the ship. Ale stench is even more primitive and stupid - they have a lot of useful skills. You can’t wash away the stench of stones. What would happen before the speech.
The scientific head of the expedition, Professor Noodles, then thought:
- In a few days I knew the way out. I came up with the idea to take the firmware of the robot Diego, a member of our crew, convert it to the firmware of the mular and give it to the wild robots.
If bad luck seemed to follow us. After a little research, it became clear that robots do not touch the connector to update the firmware. The stench is gone and there is no need for a reflash for flashing!
In fact, the only alien in the crew’s warehouse guessed that while on his home planet there was a robot that knew the programming. And not just knowing, but fixing the bugs of my powerful firmware myself.
At this very moment I was struck by a brilliant idea. It’s been a long time since I learned how to program one of the built robots in Pascal.
I told the talented young robot to be evil and learn how to program in Java. If you program it yourself, you can write your own firmware and help us!
We caught one small specimen with our hide. Diego decided to name him Amigo in honor of his brother, whom he never knew.
I paid Amigo metal with us for a month of work, and ten dollars per river for further work from the removal of the rubble. Dikuns have plenty of it, and even we are freely engaged in their enlightenment.
This is what you will later write in your memoirs:
I was overwhelmed by such uncritical plundering of my brother-in-law, but the whole team stood on the side of Professor and Risha. Of course, I waited a bit (for the sake of appearances) and tried to help Amigo learn. Hehe! The point is that no one can teach a robot better than another robot.
Everyone was so pleased with my progress that they also decided to take an active part from the Java-trained robot Amigo.
You start from the first level. Your goal is to upgrade Amigo to level 40. Alright, let's start with something small. To get the cob, go to another level. Perhaps you will be so honored that you won’t even notice when you complete the course and start practicing;)
Now let's move on to starting from scratch - press the button “Welcome to the next lecture...”.
Author's view: In total, my programming powers approximately 3 billion smartphones, 125 million TVs, and every single Blu-Ray player in the world. This language regularly takes top places in the ratings of software vendors and is the most requested among the largest IT companies. It is a technical phenomenon and operates absolutely on any device, which reflects the principle of “write once, run anywhere” (WORA - write once, run anywhere). Whoever guessed it, raise your hands! Zvichaino, tse mova Java. And today I will reveal all the cards to you and reveal all the truth about how to become a Java programmer from scratch! Vlashtovayutsya more tightly!

Java is a “fashionable” and cross-platform language programming. It works on any device with any operating system. All Google and Android add-ons are written on it. Everyday you won’t find this much information and initial materials;
The official release date for the movie is May 23, 1995. At first it was intended for an interactive cable TV channel, but it “did not mature.” Java is released by Sun Microsystems, as of 2010. purchased Oracle;
Many people confuse Java and JavaScript. If you want to do something (websites, web sites), then choose another option. Java is the back-end, so that the filling of the add-ons is developed;
JavaScript. Quick start
This is object-oriented programming, the code of which is compiled by a special Java virtual machine (JVM). In the US, approximately 9 out of 10 computers have a JVM installed;
having gained its name from the cava brand - that’s why the official emblem depicts a cup that is breathing.
Are you still here and running to get yourself a cup of aromatic cava? Todi continues with Rozmov about how to become a Java programmer.
Installation of software middleware
It’s not surprising that people have problems even at the stage of installing the Java software middleware. For this you need to go to the official website of the retailer company – Oracle. You can find the latest version at the very top of the site. You need Java SE (Standard Edition) and Java Development Kit - a set of tools for development. Please note that there are different distributions for different operating systems.
Let's say we have Windows. We go to “System Authorities” and we are amazed that our system is 32-bit or 64-bit. We are securing a file that suits our capacity. If you choose the wrong distribution, the code will be compilated and the correction will be removed. After confirming the Accept License Agreement, click the download button.
What are the Java developer tools?
Most programming is done in an IDE (IntelliJ IDEA, Eclipse, WebStorm, NetBeans). IDE is an integrated development center, a special interface for programming. It doesn’t just help with writing code, but it also makes it easier to use other programming tools. To please those who want to become a Java programmer from scratch, first write their programs in a basic notepad or Notepad++.
Maybe write some basic programs from the editor. I strongly recommend that you use the IDE. It has the functions of auto-completion of code, syntax control, transition to method assignment, and many others. And intelligent prompts relieve you of the need to remember all the function names and their parameters, which is simply physically impossible.
In a team-based work environment, where multiple people work on the same program, it is necessary to use a so-called version control system (Perforce, Git, Subversion, etc.). However, version control systems are very manual and work one at a time.
Visual algorithm for learning Java
Learn the basics of the Java language. The first lesson is the development of logical thinking skills and the development of fundamental understanding of the syntax of language programming. Once you have a book, an article or a basic video, learn how to create simple Java objects using an IDE or a text editor, which contain a variety of behavior options, depending on the input data.
Exploring the advanced capabilities of the Java language. At this stage, consider the syntax, libraries and frameworks that will be useful to you when creating more complex programs with a practical twist. A good program doesn’t just have to tinker with different libraries, but it also knows how there are stinks in the middle. In addition, concepts such as input/output operations, reduction and abstraction, serialization, generic types, regular expressions are empty words for you.
JavaScript. Quick start
Learn the basics of JavaScript in a practical application to create a web application
Subtle programming. Always avoid relying heavily on documentation and Java programming jargon. At this stage you are already able to “mutuvat” a mature programmer. Consult with Java gurus, which you will find in thematic forums and other places where programs are created. Show them your code, rejoice and please others - “accumulate karma.” You can start your own blog, publish on a new version of the official code and see what we can talk about about new advanced programs.
How can I get the programming out?
For those who want to become a Java programmer from scratch, I will tell you how to write your first program.
Well, let’s open any text editor and write:
class HelloWorld ( public static void main(String args) ( System.out.println("Hello World!"); ) )
class HelloWorld( public static void main (String args) ( System. out. println("Hello World!"); |
We save the file under the name HelloWorld.java. I appreciate that Java is case-sensitive, so the words helloworld and HelloWorld are different. If you name the file and class in the code to be deleted, the program simply will not start. Please, be careful, so that the code is ANSI.
Now we have to compile the program using the javac compiler with JDK. Until we installed the middleware, we need to compile it using the command line cmd, clicking it from the “Start” menu. In the window, type cmd and press Enter.
Since we saved HelloWorld.java in the Prog folder on drive C, then enter the command:
cd C:\Prog a |
then press Enter. In this manner, we changed the catalog to the one where our program was deinstalled. Then we enter.
Today, Java is the most popular and the most popular among all modern programs. Having started life in 1996, it was initially formed by the company Sun Microsystems. Over the years, the Oracle corporation has faded away. The developers planned to develop a universal language from Java, which would be practical for everyone.
Over the past 23 years, Java has greatly expanded and improved. The current version today is Java 11, released last spring. Over the course of this hour, Java has become more and less universally accepted. It can be called a full-fledged platform, as it has power over the ecosystem. Today's language can really be used for a number of reasons: from the creation of other programs to online portals of colossal obligations. It is often necessary to develop software on all computers, smartphones and smart technology. Most of all add-ons on Android are written in Java.
Features of Java
There are a lot of peculiarities, but the key one can be called the principle of translating code into a special bytecode There are no connections to the platform. This bytecode is then stored on the JVM. This factor distinguishes Java from other languages that are interpreted on the basis Perl, that in. Their code goes straight to the interpreter. On the other hand, Java also does not support turn-key compilations (on C-like platforms).
The unique architecture allows for cross-platform and portability of Java-based add-ons. Such products can be packaged on Windows, Linux, Mac OS, and there is no need to recompile the code. The implementation of the JVM on all platforms may vary, but the principle of the same behavior is lost.
Java's syntax is similar to that of C, even unsurprisingly. Although you are familiar with one of the C-like languages, learning Java is not difficult.
The peculiarity of language is important- it automatically collects all notes and deletes them from memory. In practice, this means that Java, without additional commands, deletes from memory objects that are not corrupted or outdated. In other languages, you need to work manually, periodically writing out subordinate commands.
Java is protected from object-oriented language. And encouragement of decline, polymorphism and other things. This approach helps create great projects that are easy to scale, expand and edit.
This is a remarkably simple language that you can easily learn. With the help of frameworks on this platform, you can use a couple of commands to create standard functionality for websites, gaming programs on PCs and smartphones, without relying on low-level code.
