Java: Stack vs Heap
Answer
The Stack stores local variables and method call frames.
In Java, the Stack is where each thread keeps its method call frames and local variables. This is crucial for method execution. When a method is called, a new frame is pushed onto the stack. For instance, in a high-traffic e-commerce site, each user's actions might lead to numerous method calls, all creating new stack frames. When the method end, the frame is popped off, and the memory is reclaimed immediately.
