Write a program that implements Baglnterface using array implementation, and create a driver class with a main method to test the implemented methods. At least 5 methods need to be tested! What is expected to be seen is: the outline of the class ArrayBag with revised constructor, revised method add, method to check initialization, methods toArray, isFull, isEmpty, getCurrentSize, get Frequencyof, contains, clear, remove, getindexOf Important part is to write comments to show your understanding and explain those methods
