Thread: Java Stack Implementation With the Help of Arrays

How can I write a program to implement a Stack using Array for this example:

Example:

Input: 
push(2)
push(3)
pop()
push(4) 
pop()
Output: 3, 4
Explanation: 
push(2)    the stack will be {2}
push(3)    the stack will be {2 3}
pop()      poped element will be 3,
           the stack will be {2}
push(4)    the stack will be {2 4}
pop()      poped element will be 4

I need suggestions for this. Thank you!

First make a design for how the program will handle a push and a pop.
What variables does the program need to have to be able to keep track of where the pushed items are stored?
How do those variables change when an item is pushed?
How do those variables change when an item is popped?
