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");
      } 
   }
}
  


Output:
