ATM Simulation System Using Java With Source Code

Introduction:

Thanks for visiting the ATM Stimulation System! This Command-Line User Interface (CLI)-based ATM Stimulation System offers a clear and easy way to execute withdrawals, deposits, and check balances. Java is the programming language used to create it. The system includes a simple command line interface with a switch case for executing deposits, withdrawals, and balance checks. It also updates the current balance after each operation. Anyone who needs to quickly calculate deposits and withdrawals should use this system. So, sit back, make a cup of coffee, and start calculating the amount in the ATM Stimulation System.

                    System.out.println("");

                case 3:
                    // displaying the total balance of the user
                    System.out.println("Balance : " + balance);
                    System.out.println("");

                case 4:
                    // exit from the menu
                    System.exit(0);
                default:
                    //default statement
                    System.out.println("Invalid Choice");
            }
        }
    }
}

This system is built using Switch Case, while loop, and Scanner class. The system will first display the user’s available options. Withdraw, Deposit, Check Balance, and EXIT are available as choices. The user must choose a useful choice. The operation will be carried out as per the input choice, and the balance will be updated following each operation. The user could also get balance information in the “Check Balance” option.
