Stack removeRange() method in Java with Example

// Java program to demonstrate the
// working of removeRange() method

import java.util.*;

// extending the class to stackyastack since removeRange()
// is a protected method
public class GFG extends Stack<Integer> {

    public static void main(String[] args)
    {

        // create an empty  stack

        GFG stack = new GFG();

        // use add() method to add values in the stack
        stack.add(1);
        stack.add(2);
        stack.add(3);
        stack.add(12);
        stack.add(9);
        stack.add(13);

        // prints the stack before removing
        System.out.println("The stack before using removeRange:"
                           + stack);

        // removing range of 1st 2 elements
        stack.removeRange(0, 2);
        System.out.println("The stack after using removeRange:"
                           + stack);
    }
}

// working of removeRange() method

        try {
            // error as 4 is out of range
            stack.removeRange(1, 4);

            System.out.println("The stack after using removeRange:"
