ATM Management System Project in Java

We will discuss the project on ATM Management System Project in Java and MySql. The article is best for projects on databases and java. There are two users: Admin and Users. Admin can add the users and users can do operations like deposit, withdrawal, pin change, and statement checking.

ATM Management System Project In Java: Project Overview

Project Name:	ATM Management System Project in Java
Abstract:	It’s a GUI-based project used with the Swing module to manage ATM transactions of a bank.
Language/s Used:	Java
IDE:	Eclipse IDE for Java Developers
Java version (Recommended):	Java SE 18.0. 2.1
Database:	MySQL
Type:	Desktop Application
Recommended for:	Final Year Students

Setting Up the environment

Make sure JDK is present in your system. It can be installed using the IDE you are using.

The first step is to create a project in the name you wish. Create a package named “atm“. We are creating java classes in this package.

To connect the project to the database, follow the steps:

Make sure MySQL is installed on your system.
Download the MySQL connector from here.
Open the properties of the project from the dropdown list which appears on right-click on the project. Navigate to the libraries tab and click on the classpath. Select “Add External JARs…”. Select the file you downloaded. This step will differ on IDE you are using.

MySQL Setup for Attendance Management System Project In Java

1. Creating the database

--CREATING THE DATABASE
CREATE DATABASE atm;

2. Selecting the database

--SELECTING THE DATABASE
USE atm;

3. Create a users table

--CREATE USERS TABLE
CREATE TABLE users(id int primary key auto_increment, card varchar(16), pin varchar(4), uname varchar(25), bal int);

4. Create a transaction table

--CREATE TRANSACTION TABLE
CREATE TABLE transactions(transid int primary key auto_increment, id int, amount int, stat varchar(3), bal int);

5. Create an admin user

--CREATING AN ADMIN USER
INSERT INTO users VALUES(1, "admin", "1234", "admin", 0);

Coding ATM Management System Project In Java

1. Main Module

File Name: “Main.java“

This module contains the main function. ie, the execution of the program begins here. This calls the login Module.

package atm;

import java.sql.SQLException;

public class Main {
	public static void main(String[] args) throws InterruptedException, SQLException {
		Login login = new Login();
		login.loginView();
	}
}

2. Login Module

File Name: “Login.java“

This module creates a page where we have to enter the ATM card numbers manually. We can also enter to admin page from this page.

package atm;

import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;

public class Login extends Commons{
	public void loginView() {
		Commons common = new Commons();
		JFrame frame = (JFrame)common.Frame();
		Font txt = new Font("", Font.BOLD, 15);
		Pin pin = new Pin();
		
		//---------------CARDNUMBER----------------
		JLabel card = new JLabel("ENTER YOUR CARD NUMBER");
		card.setBounds(50, 270, 250, 20);
		card.setFont(txt);
		JTextField cardNumber = new JTextField();
		cardNumber.setBounds(50, 300, 500, 35);
		cardNumber.setFont(txt);
		frame.add(cardNumber);
		frame.add(card);
		//-----------------------------------------
		
		//----------------ADMIN--------------------
		JLabel admin = new JLabel("ADMIN LOGIN >");
		admin.setBounds(0, 500, 570, 30);
		admin.setHorizontalAlignment(JLabel.RIGHT);
		admin.setFont(txt);
		frame.add(admin);
		admin.addMouseListener(new MouseAdapter() {
			public void mousePressed(MouseEvent e) { 
				pin.pinView("admin");
				frame.dispose();
			}
		});
		//------------------------------------------
		
		//-----------------BUTTON-----------------
		JButton cont = new JButton("COUNTINUE");
		cont.setBounds(200, 400, 200, 50);
		cont.setFont(new Font("Rockwell", Font.BOLD, 25));
		frame.add(cont);
		cont.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed(ActionEvent e) {
				if(cardNumber.getText().length() == 16) {
					pin.pinView(cardNumber.getText());
					frame.dispose();
				}
				else {
					Fail fail = new Fail();
					fail.failView("WRONG CARD NUMBER!!!");
					frame.dispose();
				}
			}
			
		});
		//----------------------------------------
		frame.setVisible(true);
	}
}

login to atm

Enter the card number in the text field and continue to enter the pin. Admin login in the bottom right helps you to log in as admin.

3. Pin Checking Module

File Name: “Pin.java“

This module checks the pin of the user is correct or not. Shows us the transaction fail page in case of the wrong password.

package atm;

import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.sql.ResultSet;
import java.sql.SQLException;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPasswordField;

public class Pin {
	public void pinView(String cardNum) {
		Commons common = new Commons();
		JFrame frame = (JFrame)common.Frame();
		Font txt = new Font("", Font.BOLD, 15);
		Home home = new Home();
		Admin admin = new Admin();
		
		//---------------PASSWORD----------------
		JLabel pswd = new JLabel("ENTER YOUR PIN");
		pswd.setBounds(50, 270, 250, 20);
		pswd.setFont(txt);
		JPasswordField pswdField = new JPasswordField();
		pswdField.setBounds(50, 300, 500, 35);
		pswdField.setFont(txt);
		frame.add(pswdField);
		frame.add(pswd);
		//-----------------------------------------
		
		//-----------------BUTTON-----------------
		JButton cont = new JButton("COUNTINUE");
		cont.setBounds(200, 400, 200, 50);
		cont.setFont(new Font("Rockwell", Font.BOLD, 25));
		frame.add(cont);
		cont.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed(ActionEvent e) {
				try {
					SQLManage man = new SQLManage();
					ResultSet rst = man.check(cardNum, pswdField.getText());
					if(rst.next()) {
						if(rst.getString("card").equals("admin")) {
							admin.adminView();
							frame.dispose();
						}
						else {
							home.homeView(rst.getInt("id"));
							frame.dispose();
						}
					}
					else {
						Fail fail = new Fail();
						fail.failView("WRONG PIN!!!");
						frame.dispose();
					}
				} catch (SQLException e1) {
					e1.printStackTrace();
				}
			}
			
		});
		//----------------------------------------
		frame.setVisible(true);
	}
}

enter pin

Type the pin to your card, for admin enter “1234” as the pin. It will take you to your respective pages.

4. Admin home page

File Name: “Admin.java“

This is the module for the admin home page. Here we have two buttons. One to add users and the other to quit.

package atm;

import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.sql.SQLException;

import javax.swing.JButton;
import javax.swing.JFrame;

public class Admin {
	public void adminView() {
		Commons commons = new Commons();
		JFrame frame = (JFrame) commons.Frame();
		
		//-------------ADDUSERS---------------------
		JButton add = new JButton("ADD USERS");
		add.setBounds(150, 250, 300, 100);
		add.setFont(new Font("Rockwell", Font.BOLD, 25));
		frame.add(add);
		add.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed(ActionEvent e) {
				AddUser user = new AddUser();
				try {
					user.addView();
				} catch (SQLException e1) {
					e1.printStackTrace();
				}
				frame.dispose();
			}
		});
		//------------------------------------------
		
		//--------------EXIT---------------------------
		JButton exit = new JButton("EXIT");
		exit.setBounds(150, 400, 300, 100);
		exit.setFont(new Font("Rockwell", Font.BOLD, 25));
		frame.add(exit);
		exit.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed(ActionEvent e) {
				System.exit(0);
			}
		});
		//---------------------------------------------
		frame.setVisible(true);
	}
}

admin home page

Add user button directs you to a page where you can add users with their current balance.

The exit button closes the application.

5. Module to add users

File Name: “AddUser.java“

This module helps the admin to add users to the database. The card number and password are generated automatically.

package atm;

import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.sql.SQLException;
import java.util.Random;

import javax.swing.JButton;
import javax.swing.JFrame;

		pinField.setEditable(false);
		frame.add(pinField);
		frame.add(atmpin);
		//----------------------------------------
		
		//-------------BALANCE------------------
		JLabel bal = new JLabel("BALANCE : ");

		auto();
		//---------------------------------------------
		
		//---------------SUBMIT-------------------
		JButton sbmt = new JButton("SUBMIT");
		sbmt.setBounds(200, 500, 200, 50);
		frame.add(sbmt);
		sbmt.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed(ActionEvent e) {
				if(!nmField.getText().equals("")) {
					if(balField.getText().equals(""))
						balField.setText("0");
					try {
						manage.adding(atmField.getText(), pinField.getText(), nmField.getText(), balField.getText());
					} catch (SQLException e1) {
						e1.printStackTrace();
					}
					success.detailView(atmField.getText(), pinField.getText());
					balField.setText("");
					nmField.setText("");
					auto();
				}
			}
		});
		//------------------------------------------
		
		frame.setVisible(true);
	}
	
	public void auto() {
		String str = "";
		for(int i=0; i<16; i++) {
			str += random.nextInt(9 - 0 + 1) + 0;
		}
		atmField.setText(str);
		str = "";
		for(int i=0; i<4; i++) {
			str += random.nextInt(9 - 0 + 1) + 0;
		}
		pinField.setText(str);
	}
}

add user

Enter name and balance to add the user into the system. The part of admin ended here.

6. Database Management Module

File Name: “SQLManage.java“

This java class does all the operations with the database. Other classes just call the method in this for all database operations to be done.

package atm;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class SQLManage {
	Connection con;
	
	SQLManage() throws SQLException {
		String usr = "root";
		String pass = "password";
		String url = "jdbc:mysql://localhost:3306/atm";
		con = DriverManager.getConnection(url, usr, pass);
	}
	
	public ResultSet check(String usr, String pass) throws SQLException {
		String str = "SELECT * FROM users WHERE card = '"+ usr +"' AND pin = '"+ pass+ "'";
		Statement stm = con.createStatement();
		ResultSet rst = stm.executeQuery(str);
		return rst;
	}
	
	public void deposit(int amt, int id) throws SQLException {
		String str = "UPDATE users SET bal = bal + "+amt+" WHERE id = "+id;
		Statement stm = con.createStatement();
		stm.executeUpdate(str);
		int bal = balCheck(id);
		str = "INSERT INTO transactions (id, amount, stat, bal) VALUES("+id+", "+amt+", 'dep', "+bal+")";
		Statement stm2 = con.createStatement();
		stm2.executeUpdate(str);
	}
	
	public int withdraw(int amt, int id) throws SQLException {
		int bal = balCheck(id);
		if(bal >= amt) {
			String str = "UPDATE users SET bal = bal - "+amt+" WHERE id = "+id;
			Statement stm = con.createStatement();
			stm.executeUpdate(str);
			bal -= amt;
			str = "INSERT INTO transactions (id, amount, stat, bal) VALUES("+id+", "+amt+", 'wit', "+bal+")";
			Statement stm2 = con.createStatement();
			stm2.executeUpdate(str);
			return 1;
		}
		return 0;
	}
	
	public void pinchange(String pin, int id) throws SQLException {
		String str = "UPDATE users SET pin = '"+pin+"' WHERE id = " + id;
		Statement stm = con.createStatement();
		stm.executeUpdate(str);
	}
	
	public int balCheck(int id) throws SQLException {
		String str = "SELECT bal FROM users WHERE id = " + id;
		Statement stm = con.createStatement();
		ResultSet rst = stm.executeQuery(str);
		rst.next();
		return rst.getInt("bal");
	}
	
	public ResultSet stmt(int id) throws SQLException {
		String str = "SELECT * FROM transactions WHERE id = " + id + " order by transid desc";
		Statement stm = con.createStatement();
		ResultSet rst = stm.executeQuery(str);
		return rst;
	}
	
	public void adding(String card, String pin, String name, String bal) throws SQLException {
		String str = "INSERT INTO users (card, pin, uname, bal) values ('" +card+ "', '"+pin+"', '"+name+"', "+bal+")";
		Statement stm = con.createStatement();
		stm.executeUpdate(str);
	}
}

7. Common Frame and Logo

File Name: “Commons.java“

This class here allows us to avoid code duplication. Calling the function in this class gets us the frame and logo on the screen.

package atm;

import java.awt.Color;
import java.awt.Component;
import java.awt.Font;

import javax.swing.JFrame;
import javax.swing.JLabel;

public class Commons {
	public Component Frame() {
		JFrame frame = new JFrame();
		frame.setSize(600, 600);
		frame.setLocationRelativeTo(null);
		frame.setLayout(null);
		frame.setResizable(false);
		frame.getContentPane().setBackground(Color.decode("#ADD8E6"));
		
		//------------------LOGO----------------------------------
		JLabel atm = new JLabel("ATM");
		atm.setBounds(0, 30, 600, 120);
		atm.setHorizontalAlignment(JLabel.CENTER);
		atm.setFont(new Font("Monospaced", Font.BOLD, 120));
		JLabel man = new JLabel("MANAGEMENT SYSTEM");
		man.setBounds(0, 140, 600, 20);
		man.setHorizontalAlignment(JLabel.CENTER);
		man.setFont(new Font("Monospaced", Font.BOLD, 20));
		frame.add(man);
		frame.add(atm);
		//-----------------------------------------------
		return frame;
	}
}

8. Success Page

import javax.swing.JLabel;
import javax.swing.JTextField;

public class Success {
	public void successView(int id) throws SQLException {
		Home home = new Home();
		Commons commons = new Commons();
		JFrame frame =(JFrame) commons.Frame();
		
		//-----------------SUCCESS------------------
		JLabel sucss = new JLabel("TRANSACTION SUCCESS.");
		sucss.setBounds(0, 280, 600, 50);
		sucss.setHorizontalAlignment(JLabel.CENTER);
		sucss.setFont(new Font("Rockwell", Font.BOLD, 25));
		frame.add(sucss);
		//-----------------------------------------
		home.homeView(id);
		frame.setVisible(true);
	}
	
	public void detailView(String num, String pin) {
		Commons commons = new Commons();
		JFrame frame =(JFrame) commons.Frame();
		
		//-----------------DETAILS------------------
		JLabel sucss = new JLabel("REMEMBER THE DETAILS!!!");
		sucss.setBounds(0, 200, 600, 50);
		sucss.setHorizontalAlignment(JLabel.CENTER);
		sucss.setFont(new Font("Rockwell", Font.BOLD, 25));
		frame.add(sucss);
		JTextField number = new JTextField("CARD NUMBER : " + num);
		number.setBounds(0, 300, 600, 50);
		number.setEditable(false);
		number.setHorizontalAlignment(JLabel.CENTER);
		number.setFont(new Font("Rockwell", Font.BOLD, 20));
		frame.add(number);
		JTextField pinno = new JTextField("DEFAULT PIN : " + pin);
		pinno.setBounds(0, 400, 600, 50);
		pinno.setHorizontalAlignment(JLabel.CENTER);
		pinno.setEditable(false);
		pinno.setFont(new Font("Rockwell", Font.BOLD, 20));
		frame.add(pinno);
		//-----------------------------------------
		frame.setVisible(true);
	}
}

transaction successful message

Here we have a page labeled “TRANSACTION SUCCESSFUL“. There is also another method executed in this class if adding users is done.

message to remember details

9. Failed Transaction Page

File Name: “Fail.java“

This Page here invokes whenever a transaction is failed.

package atm;

import java.awt.Font;

import javax.swing.JFrame;
import javax.swing.JLabel;

public class Fail {
	public void failView(String str) {
		Commons commons = new Commons();
		JFrame frame =(JFrame) commons.Frame();
		
		//-----------------FAIL------------------
		JLabel fail = new JLabel("YOUR TRANSACTIONS FAILED!!!");
		fail.setBounds(0, 280, 600, 50);
		fail.setHorizontalAlignment(JLabel.CENTER);
		fail.setFont(new Font("Rockwell", Font.BOLD, 25));
		JLabel st = new JLabel(str);
		st.setBounds(0, 320, 600, 50);
		st.setHorizontalAlignment(JLabel.CENTER);
		st.setFont(new Font("Rockwell", Font.BOLD, 25));
		frame.add(st);
		frame.add(fail);
		//-----------------------------------------
		
		frame.setVisible(true);
	}
}

wrong password message

Here the page is labeled with the string “TRANSACTION FAILED” and the reason for it.

All data for the deposit, withdrawal, changing pin, etc… are fed here. Enter the data and press SUBMIT to continue the transaction.

13. Bank statements

File Name: “Statements.java“

This module helps us in retrieving the data of transactions that we have done. This data is shown in a table.

mini statement

As we can see above, The deposit and withdrawal amounts are stated with the current balance. The latest transactions are represented first.

Output for ATM Management System Project in Java

The user Module:

The admin Module:

Conclusion

So in this project, we have learned to design a simple ATM Management System Project in Java with a database using MySQL. We can deposit, withdraw, change pin, and view statements and balances in this system. Adding user access is given to the admin.

Hope this GUI-based program helps you guys a lot!
