What is the call stack in Java?
The call stack is a special area in memory that stores information about active methods or functions. It keeps track of method calls and returns in the order they happen.

What happens when a method is called in Java?
When a method is called, a new frame is added (pushed) to the top of the call stack. This frame holds the method's parameters, local variables, and return address.

What does it mean when a method returns in terms of the call stack?
When a method finishes, its frame is removed (popped) from the call stack, and control goes back to the method below it on the stack.

What is a stack overflow error in Java?
A stack overflow error happens when the call stack runs out of space, usually because methods keep calling each other without stopping, like in infinite recursion.

How does the call stack help with debugging in Java?
The call stack shows the sequence of method calls that led to an error. This helps programmers understand where the problem happened and how the program reached that point.
