In this article we are going to see a menu driven banking application by using Java programming language.
Java Menu Driven Banking Application
We will write a program for basic banking applications which mostly involve in
- Opening Account
- Depositing Money
- Withdrawing Money
- Account Statement
For the below menu driven program, we have used below user defined method.
- openAcc( ) – Asks the user for details and creates the account
- accInfo( ) – Displays the user name, account type and account number
- balanceInq( ) – Displays the balance available
- withdraw( ) – Withdraw amount from the user account if possible.
- deposit( ) – Deposit amount into the bank account
Approach:
- Inside a while loop display all the functionalities.
- Ask the user to enter their choice.
- Use switch case for navigation.
- Upon account creation ask the user to enter their user name, account type, account number and balance. Store them all in static variables.
- Now to display the user info display the user name, account number and account type to the console.
- Now to see the the account balance, print out the available balance to the console.
- If the user want to deposit into their account, ask the user for deposit amount then add the value to the current balance and display the new balance.
- If the user wants to withdraw from the account, ask the user for withdraw amount then check if the entered amount is not greater than the balance then print the new balance after subtracting the amount, else print insufficient balance.
