        // Creating an empty Stack
        Stack<String> stack = new Stack<String>();
  
        // Use add() method to add elements in the Stack
        stack.add("Geeks");
        stack.add("for");
        stack.add("Geeks");
        stack.add("10");
        stack.add("20");
  
        // Displaying the Stack
        System.out.println("Stack: "
                           + stack);
  
        // Fetching the specific element from the Stack
        System.out.println("The element is: "
                           + stack.elementAt(3));
