Java is a popular general-purpose programming language and computing platform. It is fast, reliable, and secure. According to Oracle, the company that owns Java, Java runs on 3 billion devices worldwide. Considering the number of Java developers, devices running Java, and companies adapting it, it's safe to say that Java will be around for many years to come. This guide will provide everything you need to know about Java programming language before you learn it. More specifically, you will learn about features of Java programming, its applications, reasons to learn it, and how you can learn it the right way.

Java is platform independent
Java was built with the philosophy of "write once, run anywhere" (WORA). The Java code (pure Java code and libraries) you write on one platform (operating system) will run on other platforms with no modification. To run Java, an abstract machine called Java Virtual Machine (JVM) is used. The JVM executes the Java bytecode. Then, the CPU executes the JVM. Since all JVMs works exactly the same, the same code works on other operating systems as well, making Java platform-independent.
An object-oriented Language
There are different styles of programming. Object-oriented approach is one of the popular programming styles. In object-oriented programming, a complex problem is divided into smaller sets by creating objects. This makes your code reusable, has design benefits, and makes code easier to maintain. Many programming languages including Java, Python, and C++ has object-oriented features. If you are serious about programming.
