Library Management System Project In Java

Introduction

In this article, we will build Library Management System Project in Java and MySQL with source code. This project is great for those at an intermediate level in Java who want to advance their coding skills. In this project, the users will be able to perform the following functionalities Login, View Categories, Book details, Author details, Book issue, and Book return. Let’s get started!

Library Management System Project in Java: Project Overview

Project Name:	Library Management System Project in Java
Abstract	It’s a GUI-based project used with the Swing module to organize all the elements that work under library management.
Language/s Used:	Java
IDE	IntelliJ Idea Professional(Recommended)
Python version (Recommended):	Java SE 18.0. 2.1
Database:	MySQL
Type:	Desktop Application
Recommended for	Final Year Students

Setting the development environment

You must have java JDK installed on your system and we are using Eclipse IDE to build this project, you can use either this or Netbeans IDE.

The first step will be to create a new project. Name it as you wish. In the src folder create a library package. In that package, we will be creating some files for different modules.

To connect the system with the database you will need to follow certain steps.

Have Java JDK already installed and an IDE like Eclipse
Install MySQL on the system.
Download MySQL connector from here.
In Eclipse, under your project expand external libraries and right-click, and select Open Library Settings. Select the libraries tab and click on the + button. Browse your jar file downloaded from the above step and click on it. This will add a dependency to your project. The steps will differ if you are using a different IDE.

MySql Setup for Library Management System Project in Java

1. Create a database

-- Creating database
create database library;

2. Select the database

-- Selecting the database
use library;

3. Create a book table

-- Creating book table
create table book (
  id int primary key,
  book_name varchar(25),
  category varchar(15),
  author varchar(25),
  publisher varchar(25),
);

4. Create an issue table

-- Creating issue table
create table issue (
  member_id int primary key,
  member_name varchar(25),
  book_name varchar(25),
  date_issue date,
  date_return date
);

— Creating issue table

5. Create an admin table

-- Create admin table
create table admin (
cust_id varchar(25),
password varchar(25)
);

6. Insert some values in the admin table

-- Inserting values
insert into admin values
("admin1","1234"),
("admin2","9876");

Implementation of the Library Management System Project in Java is:

1. Login module in library management system project in java

This module helps to make a login page so that the user can enter the user name and password to enter into the library management system in java. Name the file as login.java

login page for Library Management System Project in Java

When the entered user name and password didn’t match the existing records in the database, it will return the “Username and password do not match”.

Once we enter the correct username and password it takes us to the home page of our library management application.
