Need help creating an ArrayStack class for my comp sci class. I am a beginner programmer so please keep the code as simple as possible! Your help is appreciated thank you!

Problem 2: ArrayStack.java Use an Array List to implement the Stack ADT for Strings. You should implement: public void push(String object) public String pop public String peek0 public boolean isEmpty Note, an Array List works like a dynamic array, except with the following modifications: Put at the top of your code file import java.util. To create an ArrayList of Strings, do: ArrayList 0 Where you would use: arr.addToEnd (o use instead arr.add(o) Where you would use: arr.insert(index,o) use instead arr.add(index, o) Where you would use: arr.deletelindex) use instead arr.remove(index) ArrayList does not have a built-in deleteFromend. However, you can use arr.remove(index) and arr.size) to simulate it
