Question

how could I implement an intStack class that has only a push and pop method?

in java of course.

Answer 1

// Java code for stack implementation

  

import java.io.*;

import java.util.*;

  

class Test

{   

    // Pushing element on the top of the stack

    static void stack_push(Stack<Integer> stack)

    {

        for(int i = 0; i < 5; i++)

        {

            stack.push(i);

        }

    }

      

    // Popping element from the top of the stack

    static void stack_pop(Stack<Integer> stack)

    {

        System.out.println("Pop :");

  

        for(int i = 0; i < 5; i++)

        {

            Integer y = (Integer) stack.pop();

            System.out.println(y);

        }

    }

  

  

    public static void main (String[] args)

    {

        Stack<Integer> stack = new Stack<Integer>();

  

        stack_push(stack);

        stack_pop(stack);

        stack_push(stack);

    }

}
