Here, you can: Put a new plate on top - push () Remove the top plate - pop () In the above example, we have used the Stack class to implement the stack in Java. Like an array, it contains components that can be accessed using an integer index. At an abstract level it can be described very simply, as it only allows for addition (pushing) of new and removal (popping) of existing elements from the top of the stack. peek - Read value from the top of the stack without removing it.

Stack Implementation using Array List This is an ArrayList implementation of a Stack, Where size is not a problem we can extend the stack as much as we want. To handle we need to check: 1. the current capacity of the Stack before pushing an element. The requirements of the stack are: 1) the stack has a constructor which accepts a number to initialize its size, 2) the stack can hold any type of elements, 3) the stack has a push () and a pop () method.
