public native void gc()
Description
Runs the garbage collector.
Calling this method suggests that the Java Virtual Machine expend
effort toward recycling unused objects in order to make the memory
they currently occupy available for quick reuse. When control
returns from the method call, the Java Virtual Machine has made
its best effort to recycle all unused objects.
The name gc stands for "garbage
collector". The Java Virtual Machine performs this recycling
process automatically as needed even if the gc method
is not invoked explicitly.
