Question

This has been giving me error when I try to invoke the addAccount method saying .class is expected on the line where I try to invoke it.
I am trying to do an as

Answer 1

you have declared it static so you need to add the class name before the call

bank.addAccount(int accountNo,double accountBal);

and instead of the types decleration you have to call it with parameters.

bank.addAccount(accountNo,accountBal);

Answer 2

Do not specify parameter type while calling a method.

Here is an error:

case 1 : addAccount(int accountNo,double accountBal);

It must be:

case 1 : addAccount(accountNo,accountBal); break;

Answer 3

You are missing a closing curly bracket before the definition of the displayMenu method. The following version is syntactically correct:

public class Bank {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int choice = 0;
        int accountNo = 0;
        double accountBal = 0;
        int[] accountNoArray = new int[20];
        int[] accountBalArray = new int[20];
        displayMenu();
        System.out.print("Please Enter Your Choice: ");
        choice = sc.nextInt();
        if (choice == 1) {
            System.out.print("Please Enter NRIC number: ");
            accountNo = sc.nextInt();
            System.out.print("Please Enter Account Balance: ");
            accountBal = sc.nextInt();
        }
    }

    public static void displayMenu() {
        System.out.println("Menu");
        System.out.println("1. Add an account");
        System.out.println("2.Search an account with the given account number");
        System.out.println("3.Display accounts below the given balance");
        System.out.println("4.Exit");
    }

    public static void addAccount(int accountNo, double accountBal) {

    }
}
