jvm stands for Java Virtual Machine. It is the program
which runs java programs. We can define heap size of jvm.
In java garbage collection is taken care by jvm. Hence user
need not concentrate on garbage collection. The default
algorithm jvm uses is mark and sweep algorithm. We can even
change the algorithm.
jvm is considered very useful because jvm can be hardware
and o/s dependent. But the compiled class file is
independent to be run on any platform. All this is possible
because of JVM's capability and features.
