Garbage Collection in Java: Focus on Heap Memory

Answered using GPT-4o-mini by Java Q&A Hub

Question:

Currently in Java What part of memory - Stack or Heap - is cleaned in the garbage collection process?

Answer:

In Java, the garbage collection process primarily deals with the Heap memory. The Heap is where objects are allocated, and when they are no longer reachable (i.e., there are no references to them), the garbage collector can reclaim that memory.

On the other hand, the Stack memory is used for storing method call frames, local variables, and references to objects. The Stack is managed in a last-in, first-out (LIFO) manner, and memory is automatically cleaned up when a method call completes. Therefore, the Stack does not require garbage collection; it is cleaned up automatically as part of the method execution flow.

In summary, garbage collection in Java focuses on cleaning up the Heap memory, while the Stack is managed automatically by the Java runtime.
