What is JVM and its role? What is the feature of platform independency in Java? How does it differ ..

Answer / sunil.hit

JVM is java virtual machine.

when we say that its platform independent it doesn't mean we dont required it on our desktop or laptop.
it just means that you just need that JVM file to run all java application over your machine.
it automatically comes with all the OS now a days. so you dont required to install that JVM file.
otherwise...

when ever you are connected with internet and you are downloading any java application
the server at the other side send your machine that JVM file
it then install automatically or it will create a dummy.
and when the application is install to use it will not through any error.
JVM file will be supported by all OS since its global .
that makes it platform Independent.

whereas in C++ dont have such file, it is needed to be install or copy all the file to your machine.
