INTRODUCTION TO JVM

JVM : JAVA VIRTUAL MACHINE

Virtual machine: gives a program a simplified interface for

interacting with a variety of physical computers and their operating systems.

JAVA VIRTUAL MACHINE

JVM is a software layer which resembles an hardware platform.

JVM converts Java byte code into machine language and executes it.

The byte code can be executed on any platform where there exist JVM.

JVM‘s are available for many hardware and

software platforms.

JAVA::"write once, run anywhere”: use of the same byte

code for all JVM’s on all platforms.

JAVA is platform independent.
