Program Code: (StackProg.java) 

import java.util.*; public class StackProg {       public static void main(String args[]) {       Stack st = new Stack();       int top;       System.out.println("stack: " + st);       st.push(42);       System.out.println("stack: " + st);       st.push(66);       System.out.println("stack: " + st);       st.push(99);       System.out.println("stack: " + st);       top=(int)st.pop();       System.out.println("stack: " + st);       top=(int)st.pop();       System.out.println("stack: " + st);       top=(int)st.pop();       System.out.println("stack: " + st);       try {       top=(int)st.pop();         }       catch(EmptyStackException e)       {         System.out.println("Empty Stack");       }     } }
