How many garbage collectors are there in Java?

Which is the best garbage collector in Java?

How is parallel garbage collector different from serial garbage collector?

Parallel Garbage Collector is same as Serial Garbage Collector because Parallel Garbage Collector also freezes the running threads of the application while performing the garbage collection. But the difference is, Parallel Garbage Collector uses multiple threads to perform cleaning of unused heap area.

Can a JVM override a garbage collector method?

Based on our requirement, we can override finalize () method for perform our cleanup activities like closing connection from database. The finalize () method called by Garbage Collector not JVM. Although Garbage Collector is one of the module of JVM.
