HW | Java IronLibrary (Unit 3 homework)

Introduction

For this homework, you will be building a Library Management System, that will help managing and acquiring data about the books that are being used by students.

Instructions

Let's walk through the details of the homework:

Classes

Four main classes are necessary to complete this homework.

These classes will be called Author, Book, Student and Issue.

• Variable called returnDate of data type string (Private member)
• Variable called issueStudent of data type Student, representing a One-to-One relationship with Student(Private member)
• Variable called issueBook of data type Book, representing a One-to-One relationship with Book (Private member)
• A parameterized constructor that takes issueDate, returnDate, issueStudent and issueBook
• Public Getter functions to access these variables

• Optional attributes are accepted if needed based on the code structure

Student class

This class will have:

• Variable called usn of data type string, representing the Universal Student Number and acting as the unique identifier for the table student (Private member)
• Variable called name of data type string (Private member)
• A parameterized constructor that takes usn and name
• Public Getter functions to access these variables
• Public Setter functions to change these variables
• Optional attributes are accepted if needed based on the code structure

How the application works

After starting this application, a list of options will pop up for the user.

Requirements

For this project, you must accomplish all of the following:

1. Navigate through a text-based menu using Standard Input and Output.
2. Create unit tests for every method other than basic getters, setters and constructors (getters and setters with logic do require unit tests).
3. Handle all exceptions gracefully (incorrect input should not crash the program).
4. All data should be stored in a normalized SQL database.

Bonus

1. Add more options that can help display more information such as List books to be returned today, etc.

Important Notes

• Everyone in the squad should contribute equally to the project in time and lines of code written.
• All code must be reviewed before it is merged into the master branch.
• All squad members must participate in code review.
• Every repository should have a README file with clear instructions, demo files, or any documentation needed so other teams don't have problems with the review.
• This is intended to be a challenging assignment. You will have to rely heavily on your teammates and independent research. Learning independently is a hallmark of a good developer and our job is to turn you into good developers. This process may be frustrating but you will learn a ton!
