Question: 1 / 510

What is garbage collection in Java?

A process to clean up unused Java objects.

Garbage collection in Java refers to the automatic process of removing unused objects from memory. This means that when an object is no longer being referenced by any part of the program, it will be deleted from memory by the garbage collector. Option B is incorrect because garbage collection does not involve deleting entire instances of classes, but rather cleaning up unused objects within those instances. Option C is partially correct, as garbage collection does involve keeping track of object references, but that is not the main purpose of the process. Option D is incorrect because garbage collection is an automatic process and does not require manual intervention.
