ASSIGNMENT DESCRIPTION

In this assignment you will be implementing a basic Bank Account class. Some goals for this assignment are to learn how to implement an interface and how to write code to build an object based on an implemented class.

OVERVIEW

You are given an interface called BankAccountInt,

You need to create a class called BankAccount that implements the BankAccountInt interface.

You need to create a class Program to test your code and ensure that your class correctly implements the interface.

DETAILS

The BankAccountInt interface:

An interface is a contract. programmers must implement all of the methods that the interface lists.

The BankAccount class that you will be writing $($see below$)$ must implement the BankAccountint interface.

Download BankAccountInt.java darr, and into your project folder in Eclipse.

You will need to read the comments above each method declaration in BankAccountInt.java to see what each method is supposed to do$.$

You do not modify BankAccountInt.java. You will be adding your code to BankAccount.java.

The BankAccount class:

This is the class that you will need to create to implement the BankAccountint interface you downloaded earlier.

In the Package Explorer, select the edu.sbcc$.$cs$105$ package $|$ New $|$ Class.

In the wizard, set the name to BankAccount. Then click the Add $($interface$)$ button, and search for BankAccountInt. Check the "Inherited abstract methods" box. Click Finish. Eclipse will create the class and automatically add method stubs that meet the BankAccountInt interface.

You will need to read the comments above each method declaration in BankAccount$/$nt$.$java to see what each method is supposed to do$.$

In addition to implernenting BankAccountInt interface, the BankAccount class must also implement the Comparable
