Problem 2: ArrayStack.java Use an ArrayList to implement the Stack ADT for Strings. You should implement: • public void push(String object) • public String pop() • public String peek() • public boolean isEmpty() Note, an ArrayList 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<String> arr = new ArrayList<String>(); • Where you would use: arr.addToEnd(o) use instead arr.add(o) 1 • Where you would use: arr.insert(index,o) use instead arr.add(index, o) • Where you would use: arr.delete(index) 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.
