Characteristics of Java
The target of Java is to write a program once and then run this program on multiple operating systems.
Java has the following properties:
- Platform independent: Java programs use the Java virtual machine as abstraction and do not access the operating system directly. This makes Java programs highly portable. A Java program which is standard complaint and follows certain rules can run unmodified all several platforms, e.g. Windows or Linux.
- Object-orientated programming language: Except the primitive data types, all elements in Java are objects
