Supply Chain Management System in Java

Supply Chain Management System in Java

In this article, we will build Supply Chain Management System in Java and MySQL with source code. In this project, the users can perform the following functionalities Login, Add Suppliers, View Product details, Add Products, and Purchase Products. Let’s get started!

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 Supplychain 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 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 Supply Chain Management System Project in Java

1. Create a database

-- Creating database
create database supplychainmanagement;

2. Select the database

-- Selecting the database
use supplychainmanagement;

3. Create a supplier table

-- Creating supplier table
create table supplier(
  id int primary key,
  suplier_name varchar(25),
  email varchar(15),
  password varchar(25),
);

4. Create a product table

-- Creating product table
create table product (
  product_id int primary key,
  product_name varchar(25),
  quantity int,
  price int
);

Implementation of the Supply Chain Management System in Java

First, we need to create a class DbConnection to connect our database to the program

DBConnection.java

import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.logging.Level;
import java.sql.Connection;
import java.util.logging.Logger;

public class DBConnection {
    public Connection con;
    String url ="jdbc:mysql://localhost:3307/supplychainmanagement";
    String db = "supplychainmanagement";
    String user = "root";
    String pass = "";
    
    public Connection mkDataBase() throws SQLException{
        try {
            Class.forName("com.mysql.jdbc.Driver");
            con = DriverManager.getConnection(url, user, pass);
           
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
     
        }
        return con;
    }
}

1. Login module

This module helps to make a login page so the user can enter the user name and password to the Supply Chain management system in Java. Name the file login.java.

import java.awt.*;
import javax.swing.*;
import javax.swing.colorchooser.AbstractColorChooserPanel;
import java.awt.event.*;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;

public class Login extends JFrame{
    JLabel idLabel;
    JLabel passLabel;
	JLabel background;
	JLabel headerLabel;
	JLabel devInfo;
    JTextField id;
    JPasswordField pass;
    JButton submit;

   public Login(){
		setTitle("Supply Chain Management System");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setVisible(true);
		this.background = new JLabel(new ImageIcon("C:\\Users\\ELCOT\\Downloads\\Bg.png"));
		//mainFrame.getContentPane().setBackground(Color.white);
		this.init();
		add(background);
		background.setVisible(true);  
        this.pack();
		this.setSize(700,400);
		this.setLocationRelativeTo(null);
    }

    public void init(){
		headerLabel = new JLabel();
		//this.headerLabel.setText("Supply Chain Management System");
		this.headerLabel.setBounds(190,1,370,150);
		this.headerLabel.setFont(new Font("Geomanist", Font.BOLD, 20));
		headerLabel.setForeground(Color.red);
		add(headerLabel);
		
		idLabel = new JLabel();
		this.idLabel.setText("Username");
		this.idLabel.setBounds(190,110,100,50);
		this.idLabel.setFont(new Font(null, Font.BOLD, 20));
		idLabel.setForeground(Color.black);
		add(idLabel);
		
        passLabel=new JLabel("Password");
		this.passLabel.setBounds(190,165,100,50);
		this.passLabel.setFont(new Font(null, Font.BOLD, 20));
		passLabel.setForeground(Color.black);
		add(passLabel);
		
		devInfo = new JLabel();
		this.devInfo.setText("");
		this.devInfo.setBounds(130,300,1000,30);
		this.devInfo.setFont(new Font("Geomanist", Font.PLAIN, 15));
		devInfo.setForeground(Color.white);
		add(devInfo);
			
		id=new JTextField();
		this.id.setBounds(300,125,200,30);
		add(id);
		
		pass=new JPasswordField();
		this.add(pass);
		this.pass.setBounds(300,175,200,30);
		this.id.setVisible(true);
       this.submit=new JButton("Login");
	   this.submit.setBounds(400,230,100,25);
	   add(submit);
       submit.addActionListener(this::submitActionPerformed);
    } 

   public void submitActionPerformed(java.awt.event.ActionEvent evt){
   if(id.getText().equals("admin") && pass.getText().equals("admin")){
     this.hide();
     Frame2new fn=new Frame2new();
     fn.showButtonDemo();
   }
   else{
    JOptionPane.showMessageDialog(null, "Invalid password!");
   }
   }
}
class MyGui{
	public static void main(String[] a){
		Login l = new Login();
		l.setVisible(true);
	}
}
