Creating a new stack from an exisiting one.

Cross-posted to 2 groups.

I have stack like the following..

[1, 4, 10, 20]

What I need to do is pop the top item off the stack such that it looks
like the following..

[1, 4, 10] [20]

Then, starting at [20], I need to be able to push the numbers 78 and
99 onto this stack such that the output looks like

[1, 4, 10] [20, 78, 99]

Can this be done without creating a new stack? If so how? I just need
some general idea.  Here is what I came up with so far..

import java.util.*;

public class funcTest {


    public static void main(String[] args) {
        Stack<Integer> stack = new Stack<Integer>();
        stack.add(1);
        stack.add(4);
        stack.add(10);
        stack.add(20);

        System.out.println(stack);

        Object temp = stack.pop();

        System.out.println(stack + " " + "["+ temp + "]");

        //This part from here on down doesn't work
        /*
        stack = (Stack)temp;
        stack.push(78);
        stack.push(99);

        System.out.println(stack + " " + "["+ temp + "]");
         *
         */
    }//end main()

}
