    Default ATM Program HELP

    ok so i have this file and in it, it has:
    lastName firstName accountNumber accountPassword accountBalance

    so i want my program to ask the user for the accountNumber and the accountPassword and to go into the file i have and check if they match and if the do it prints the firstName and lastName.

    so far i cant make it check and match accountNumber and the accountPassword and it prints everything in the file, i know i have to implement so type of array

    atmFile(String lastName, String firstName, int accountNumber,int accountPassword, double accountBalance) but i just cant make it work, any tips?
