The phenomenon of Java popularity

Java language is universal and is used everywhere: mobile applications and games, scientific developments and mobile phones, game consoles, and complicated supercomputers. Java is the foundation for almost all types of networking applications. Many studies call it the #1 programming language among developers.

Java as the first programming language

The basics in learning Java are often given even in secondary specialized educational institutions. It is the foundation of teaching programming in American schools. For this reason, it often becomes the first language on the programmer’s list. All further languages taught in college are always compared to Java. Even in the case of switching to another language, the basic knowledge is still based on Java.

This language has many advantages that make it a leader in the study of computer science. Yes, not everyone likes to manually specify data types, considering it a kind of “airbag”. However, this is a good opportunity for beginners to understand the basic principles of a PC.

This is annoying to many, and it takes too much time to format the braces. There are many fancy languages that don’t need curly braces. In some, this is really inconvenient, but for beginners they are useful. With their help, it is easier to understand the general principles.

What are the advantages of Java?

Let’s have a look at the advantages of this programming language.

Cross-platform. Java has a special program that executes code – the Java Virtual Machine. We write the program code only once, and it works with any hardware platform or operating system: from smart cards to applications for smart homes.
Community. As we have already said, Java is a fairly widespread language: it is used by a large number of developers, and someone has already come up with a solution to almost any problem that may arise when working with Java. Thanks to thousands of libraries and forums, you can find a ready-made solution for almost any situation. GitHub, for example, has open-source projects and documentation, and the Stack Overflow forum offers community help.
Great emphasis on safety. Java is one of the most important programming languages that has been at the top of various rankings for many years. This is especially appreciated by institutions that process large amounts of data to be billed or transacted. This scale and the global brands behind it have made the systems of large corporations, including banks, based on Java, a testing ground for hackers. The hacker attacks sparked a reaction from the victimized organizations, creating ever more robust barriers. As a result, security systems were frequently updated, corrected, and modified. Thus, it can be said that Java is the most advanced language when it comes to maintaining security.
Strongly typed language. Java is a strongly typed language. This means that the data must be of a specific type. Otherwise, the program will not work. Thanks to this, it is more resistant to errors. Large corporations, banks, and financial holding companies value decisions over which they have complete control, and that’s what Java guarantees them.
Object-oriented. All libraries ever written for Java are classes that are responsible for the functionality of the language. Any Java application is a set of classes that describe different objects. This is good because it allows you to create complex programs that are easy to maintain. And in general, Java is a multi-paradigm language, that is, it supports many programming principles, which allows you to effectively solve various problems.
Relative simplicity. Working with Java is not as easy as with Python, but it is much simpler than C or C ++. The functionality of the language is updated slowly, so you can easily switch to new versions – you don’t have to re-learn. Java is a strongly typed language, which means that a beginner will always have the opportunity to see an error in the code when compiling.
Flexibility. Using Java, you can develop a program of any complexity: an online store, banking applications, high-load systems, and even artificial intelligence.

All this makes Java a great language for newcomers to programming.

What sites and programs run in Java

It’s probably easier to say who doesn’t use Java on the Internet. Amazon.com – the most popular online store – is written in this language; the back end of eBay, the entire set of functions of the Android operating system, and even the special effects in the movie “The Avengers” are created using Java.
