When the method finishes executing, the values on the stack are popped off, and the memory is freed up for other uses. Heap space in Java is much bigger than the Stack memory. As the method executes, it may push additional values onto the stack, such as intermediate results of calculations. Instead, more space will be allocated as needed. Unlike the stack, the engine doesn't allocate a fixed amount of memory for these objects. The heap is a different space for storing data where JavaScript stores objects and functions.

When a method is called, the values of the arguments are pushed onto the top of the stack. The limits of these values and the entire stack vary depending on the browser.

In Java, stack memory refers to the part of a computer's memory that is used to store local variables, method arguments, and intermediate results of calculations while a method is executing. How does stack memory work in Java, including PUSH and POP operations? In summary, stack memory is a useful tool for organizing and managing the flow of a program. This helps to keep track of what the program is doing and ensures that tasks are completed in the proper order. The stack is generally smaller in size than the heap because it is used for storing small, temporary variables and data, while the heap is used for storing. The items at the top of the stack are the ones that are currently being worked on, while the items at the bottom are waiting their turn. You can take stack memory as a to-do list for your Java program.
