Enumerate the concept of write once run anywhere - JAVA
Java has introduced concept of WORA (write once run anywhere). When you write a java program it is called source code of java. Java compiler doesn't compile this source code for any underlying hardware system; rather it compiles it for a software system called JVM (This compiled code is called byte code). We have different JVMs for different systems (for example JVM for Windows, JVM for Linux etc.).
