Restaurant Management System Project In Java

Introduction

In this article, we will build Restaurant 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, Add food items, update food, delete food, and generate bills. Let’s get started!

Restaurant Management System Project in Java: Project Overview

Project Name:	Restaurant Management System Project in Java
Abstract	It’s a GUI-based project with the Swing module to organize all the elements under restaurant management.
Language/s Used:	Java
IDE	IntelliJ Idea Professional and Eclipse(Recommended)
Java 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 restaurantmanagement 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 specific steps.

Have Java JDK already installed and an IDE like Eclipse
Install MySQL on the system.
Download the MySQL connector from here.
In Eclipse, under your project expand external libraries and right-click, and select Open restaurantmanagement 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 Restaurant Management System Project in Java

1. Create a database

-- Creating database
create database restaurant;

2. Select the database

-- Selecting the database
use restaurant;

3. Create a food table

-- Creating food table
create table food (
  id int primary key,
  food_name varchar(25) not null,
  price int not null,
  quantity int 
);

4. Create an admin table

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

5. Insert some values in the admin table

-- Inserting value in admin table
insert into admin values
("admin","admin")

Implementation of the Restaurant Management System Project in Java

1. Login module

Conclusion

In this project, we developed a GUI-based project, a Restaurant Management System Project in Java and MySQL. The users are able to perform the operations such as Login, Adding food items, updating food, deleting food, and generating bills. I hope you enjoyed doing this project!
