import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a stack
    Stack<Integer> MyStack = new Stack<Integer>();

    //populating stack
    MyStack.push(10);
    MyStack.push(20);
    MyStack.push(30);
    MyStack.push(40);
    MyStack.push(50);

    System.out.println("Before method call, MyStack contains: " + MyStack);
    MyStack.set(1, 1000);
    System.out.println("After method call, MyStack contains: " + MyStack);    
  }
}

The output of the above code will be:

After method call, MyStack contains: [10, 1000, 30, 40, 50]
