Java courses

IT specialties today are in much higher demand in the labor market. Even those who have qualifications in other fields are increasingly deciding to change careers in favor of IT. Moreover, age, education, and abilities do not play a big role: the industry is wide enough and many people can find their place. Here, it is possible to find work of a technical nature, as well as analytical and more creative. There are different programming languages, algorithms, scripts, and so on. All of these technologies are used in manufacturing, commerce, service, education, and in people's daily lives. Considering so many options, there is a high demand for information technology specialists. Therefore, it is quite realistic to be trained and get a prestigious job. It is only necessary to choose the most appropriate area, gain a theoretical basis, and build up initial experience. You can do all this at DevEducation programming courses. The educational platform provides a convenient format of study, in-depth knowledge, and highly qualified practicing teachers. A certificate from DevEducation and completed tasks in the portfolio will significantly improve the graduate's position among candidates for jobs at large international IT corporations.

Java: A multifunctional programming language

A window of opportunity for the beginner opens up by learning Java. This high-level language was developed by the American company Sun Microsystems, and the new product hit the market in 1995. It operates on different electronic platforms: Windows, Mac, and different versions of UNIX. What is Java? It is a typed object-oriented programming language for general use by users. It was created by experts from the Java Community Process, and it is distributed under the GPL license. Oracle owns the trademark. Programs written in Java are often translated into byte code, making them usable on all computer architectures implemented through the Java virtual machine. The versatility of JAVA is confirmed by the slogan, "Write once, run anywhere." The popularity of using the product is confirmed by the official ratings: the second position in the lists of IEEE Spectrum for 2020 and TIOBE for 2021. Now there are different versions of the language for different needs: in particular, applications for enterprises are created in J2EE, for mobile extensions — in J2ME.

7 facts about popular programming language

Let's take a look at the features of Java:

1. The development was intended as an assistant in the programming of household electrical appliances, but over time, experts have discovered many other useful features.
2. This is a fairly stable programming language: it can be used to read codes that are more than 20 years old. That is why Java is highly valued by the world's major companies, especially those in finance. For example, among its consumers are such corporations as eBay, Amazon, Intel, Oracle, Citigroup, IBM, Goldman Sachs, and Barclays.
3. The popularity of the product is confirmed by international ratings: according to TIOBE, it is in the second position among languages. The list is based on the number of developers who use Java, suggestions for learning this type of programming, and other parameters. According to ORACLE, the number of gadgets working with this language, to date, is more than three billion.
4. Developers in this programming language are highly paid for their work. The Ukrainian market offers an average salary for a Junior level specialist of about $800, a Middle — $2,000, a Senior — about $3,600, and an Architect can earn up to $6,000.
5. Projects for the Android operating system are created in Java. It is used along with Kotlin, but it is impossible to learn it without knowledge of Java.
6. The development works on the WORA principle. That is, "write once, run anywhere." Thus, programs can be run in any JRE runtime environment.
7. Java has a history of large amounts of code, it needs constant support. Therefore, Java developers are highly valued and in high demand in the labor market around the world.

Why professionals choose Java

The object-oriented programming language is highly typified. The basic principle of Java is to write code for a program once so that it can then be applied in different places with an available runtime environment. Development helps create applications for smartphones, tablets, virtual gaming devices, supercomputers, and PCs. What you need to know about the advantages of Java:

• Cross-platform nature. As we mentioned earlier, the same code is suitable for creating applications on different operating systems and hardware platforms.
• The code is very reliable. Because of the high typing, the developer will have a more precise type to fit any expression or variable. The compiler allows to quickly and clearly identify the problem and work on fixing it.
• Multitasking. Due to the flexibility of the programming language, it can participate in the development of different programs. These are both common entertainment applications, e-commerce, and highly loaded systems.

What are the reasons for the high demand for Java training in 2022:

• The language has existed for many years. Nevertheless, it is still widely used today.
• Since many industries use Java for their development, there are plenty of job offers for specialists to write this code.
• The learning process is quite simple. The language is not characterized by too frequent feature updates. At the same time, there is support for previous features for each new version of Java.
• Expanded capabilities. Once we have learned java, it is much easier to start learning C languages. These include C#, C and C++, JavaScript, and Solidity.
• Powerful community of Java specialists. While working with the code, the developer can seek help from various thematic forums, websites, and libraries that will provide technical support and practical advice.

About the technical advantages of using Java

Let's take a look at the technical advantages of this programming language:

• It's object-oriented: Java presents everything as an object. All add-ons are quite easy to expand since they are based on the object model.
• Platform independence: compared to other languages such as C and C++, for example, Java does not compile on a specific device, instead, it compiles in independent byte code. It is promoted on the Internet and is also interpreted in the Java Virtual Machine (JVM).
• Simplicity. It's easy to learn and start coding in a programming language. For those professionals who are aware of the basis of operation of an object-oriented system, the process of understanding Java is simplified, and they will quickly be able to grasp the knowledge base.
• Safety. Platform authentication is designed on public-key encryption.
• The language is architecturally neutral. The compiler projects architecture-neutral volumes in file format. Thus, the compiled code can run on many processors, including the Java Runtime system.
• Portability. Complementing the previous point, the language does not depend on the implementation of aspects of the specifications. The compiler is built in ANSI, which has pure portability — a subset of POSIX.
• Accuracy. It works to eliminate errors in different positions, focusing on parameters such as compile time and checking for runtime errors.
• Multithreading. A special feature allows the development of applications to perform multiple tasks simultaneously. It allows programmers to work on fine-tuned interactive programs.
• Interpretability. The system translates Java byte code into machine-type instructions, which are not stored.
• High performance. The just-in-time compiler greatly increases performance.
• Dynamics. Java is more adaptable to different conditions than C or C++. There are many functions that do not interfere with the data processing to analyze and provide access to various objects.
• To accessibility, we add the ability to support work in distributed Internet conditions.
