INTERVIEW QUESTIONS J2EE JAVA DETAILS

Question: Describe, in general, how java's garbage collector works?

Answer: The Java runtime environment deletes objects when it determines that they are no longer being used. This process is known as garbage collection. The Java runtime
environment supports a garbage collector that periodically frees the memory used by objects that are no longer needed. The Java garbage collector is a mark-sweep
garbage collector that scans Java's dynamic memory areas for objects, marking those that are referenced. After all possible paths to objects are investigated, those objects
that are not marked (i.e. are not referenced) are known to be garbage and are collected.
