Java is one of the most popular programming languages. It is versatile and has been in use for over 20 years
The versatility is provided by the Java Virtual Machine (JVM). In many languages, at compile time, a program is translated into code that can work differently on different devices or platforms. Java doesn’t have this problem. The JVM acts as a middleware — from a Java program, it makes code that can run on any computer, regardless of where the code was compiled.
Java has a large community, and on the Internet you can find answers to almost any question about the language.
