To create a collection object

Mystack ms = new mystack ();

adding elements

Ms.add ("Hello");

Ms.add ("World");

Ms.add ("Java");

System.out.println (Ms.get ());

System.out.println (Ms.get ());

System.out.println (Ms.get ());

Nosuchelementexception

System.out.println (Ms.get ());

The following code is for the above //System.out.println (Ms.get ()), and so on, and so on, in addition to the code to pop up the element, you can also determine whether the stack is empty

while (! ms.isempty ()) {

System.out.println (ms.get ());

}

}
