So, Lets get started from the basic questions....

1) what is java?

JAVA is a programming language just like C,C++ or C#. JAVA is Object Oriented Language. Java is developed by Sun Microsystems (1995). It is platform independent as well. It needs JDK (Java Development Kit). This also includes JVM (JAVA Virtual Machine..It is a Virtual machine that executes byte code on specific platform). This the the thing which makes java platform independent. JAVA byte code in compiled form can run on any machine with any architecture with the help of JVM (Here onwards we will refer JAVA Virtual MAchine as JVM...nice name ehh?).
