import java.util.*;

public class StackDemo {
   public static void main(String args[]) {
      Stack st = new Stack();
      st.push("Java");
      st.push("Source");
      st.push("code");
      System.out.println("Removed object is: "+st.pop());
      System.out.println("Elements after remove: "+st);
   }
}
