ATM Machine Project in Java Programming with Code

Doing experiments and new projects while learning a programming language is really fun and exciting. We are going to make a simple ATM machine project using java programming. ATM stands for Automated Teller Machine. It's possible to make a complete functional ATM project and GUI in java. But we are going to make a simple one in this article.

ATM Machine Project in Java Programming with Code

In our simple ATM project, the user can deposit money, withdraw, check account balance, and exit from the ATM program.

Key Features of the ATM Machine project:

• The java Program can Display the ATM Transaction
• The user can deposit money from this ATM Machine project
• The user can withdraw cash from this ATM Machine project
• The user can check the bank account balance

ATM users can deposit money to the bank by choosing the deposit option. The java program will simply get the deposit amount from the user and add the money to the user's account.

Users can withdraw money from their bank account through the program by selecting the withdrawal option. After a successful transaction, the ATM machine will deduct the amount from the central bank account.

The user can also check their existing bank account total balance using the checking account balance option. 

Finally, the exit option will simply exit the users from the ATM machine program and return the user to the default main menu.

ATM Machine Java program:

Let's design an ATM machine project using java programming. In this ATM machine, we are going to use which case statement. Let's look at the java code for the ATM machine project.

	//import required classes and packages
	import java.util.Scanner;
	//create ATMExample class to implement the ATM functionality
	public class ATM_Machine
	{
	//main method starts
	public static void main(String args[] )
	{
	//declare and initialize balance, withdraw, and deposit
	int balance = 0, withdraw, deposit;
	//create scanner class object to get choice of user
	Scanner sc = new Scanner(System.in);
	while(true)
	{
	System.out.println("ATM Machine\n");
	System.out.println("Choose 1 for Withdraw");
	System.out.println("Choose 2 for Deposit");
	System.out.println("Choose 3 for Check Balance");
	System.out.println("Choose 4 for EXIT\n");
	System.out.print("Choose the operation:");
	//get choice from user
	int choice = sc.nextInt();
	switch(choice)
	{
	case 1:
	System.out.print("Enter money to be withdrawn:");
	//get the withdrawl money from user
	withdraw = sc.nextInt();
	//check whether the balance is greater than or equal to the withdrawal amount
	if(balance >= withdraw)
	{
	//remove the withdrawl amount from the total balance
	balance = balance - withdraw;
	System.out.println("Please collect your money");
	}
	else
	{
	//show custom error message
	System.out.println("Insufficient Balance");
	}
	System.out.println("");
	break;
	case 2:
	System.out.print("Enter money to be deposited:");
	//get deposite amount from te user
	deposit = sc.nextInt();
	//add the deposit amount to the total balanace
	balance = balance + deposit;
	System.out.println("Your Money has been successfully depsited");
	System.out.println("");
	break;
	case 3:
	//displaying the total balance of the user
	System.out.println("Balance : "+balance);
	System.out.println("");
	break;
	case 4:
	//exit from the menu
	System.exit(0);
	}
	}
	}
	}
