Java Virtual Machine Stacks

• Each Thread in a JVM has a private Stack allocated, It is called Java Virtual Machine stack for that Thread.
• Here, each stack stores Frames(read topic Frames for understanding)
• Stack holds local variables, partial results, and it involves in calling a Method.
• Stack never altered directly, but it manipulated by pop and push operations.
• Memory allocated for the Stack is not required to be contiguous.
• Stack size can be fixed or it can be allocated dynamically.
