Design a Bank Account Application that will allow users to do their transactions. For this, user will have to enter all the required information like, name, account number, account type and initial balance etc and using the switch case statement they can select the type of transaction they want to do, and they get information regarding their balance also. The type of transaction to carry shall include the following; Depositing of money, withdrawing, statement of account, user details and exiting the application. You should let the user at least enter like three deposits Note: In this application you may have to generate several function and use several programming statements. The functions to create may include; Withdraw, Deposit, Accounts details etc. below is a sample of how a function may be created;

int deposit() {

System.out.print("Enter amount to deposit:");
amt = input.nextInt();
if (Deposit< 0) {
System.out.println("Invalid Amount");
return 1;
} Total = bal + Deposit;
return 0;
}
