How does it work?

Java is purely an object-oriented language. You'll learn what that means and how to use it in the upcoming lessons. For now, just know that object-oriented programming is very convenient and popular. Programmers prefer Java because the code written in this language is easy to understand and extend.

In addition, Java is a cross-platform programming language. Let's take a look at how this cross-platform capability works:

Java is known for its Write Once, Run Anywhere principle, which is made possible by the JVM (Java Virtual Machine). You can learn more about the JVM in this article.

The JVM converts the code we write into machine bytecode, which can be understood by any system or computer. This means you can even run Java code on a refrigerator (as long as the refrigerator has a Java compiler installed).

These and many other factors make Java a top choice for development.
