import java.util.*;
  
public class StackDemo {
    public static void main(String args[])
    {
  
        // 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");
  
        // Output the Stack
        System.out.println("Stack: " + stack);
  
        // Remove the element using remove()
        boolean res = stack.remove("20");
  
        // Print the removed element
        System.out.println("Was 20 removed: "
                           + res);
  
        // Print the final Stack
        System.out.println("Final Stack: "
                           + stack);
    }
}
