Hi, I need help writing a program that demonstrates the usage of BAGS in JAVA. This program is for my intro to data structures.

Below, are some of the instructions my instructor has asked me to do:

I would greatly appreciate it, if task 2 was completed, but I primarily need help on task 1 to get started.

THANK YOU! Will rate!

Purpose: I. Warm up your programming skills. 2. Understand the interface and application of bags Task Description: Task 1: Imagine a pile of books on your desk. Each book is so large and heavy that you can remove only the top one from the pile. You cannot remove a book from under another one. Likewise, you cannot add a book beneath another one. You can add another book to the pile only by placing it on the top of the pile. If you represent books by their titles alone, design a class that you can use to track the books in the pile on your desk. Specify each operation by stating its purpose, by describing its parameters, and by writing a pseudocode version of its header. Then write a Java interface for the pile's methods. Please follow the code examples in our lecture slides to comment your code. Task 2: Define a class PileOfBooks that implements the interface described in Task 1. Use a resizable array in your implementation. Then write a program that adequately demonstrates your implementation
