What is stored in the JVM stack area during program execution?

In the JVM (Java Virtual Machine), the stack is used to store information related to method execution. The stack area stores:

• Local variables of the method (primitive types and object references).
• Operands for performing operations (operands are pushed to and popped from the stack during bytecode execution).
• Information about method calls (stack frames), including return addresses.

Each method call creates a new frame in the stack, which contains local variables and operands for that method. After the method completes, the frame is removed from the stack.

It is important to note that objects themselves are stored in the heap, while the stack only stores references to them and primitive values.
