<b>Garbage Collection in Java</b>

In Java when program executes the JVM creates the object of the Java classes which is to be executed. In this process these objects are stored into memory. When these objects are not need the JVM process removes these objects and then reclaims the memory. This process of finding the unused Java objects and then freeing objects which is no longer is in use is called the Garbage Collection.
The Garbage collection process is automatic and programmer can?t free the un-used objects. Only JVM automatically runs the Garbage collection process.
The Garbage collector is responsible for running the Garbage collection process in Java.
