package atm; /* File: ATM.java * Author: Andress Quinton * Date: Feb 2, 2017 * Purpose: CMIS 242 Project 2 * - This will create a GUI that will have 4 buttons,2 radio buttons, * and a text box * - The user will be able to enter an amount in the text box * and select ether checking or saving account * -- If the user enters a non-numerical input a message will display * Informing the user to enter a valid amount * - After this the user, can select withdraw, transfer, or deposit * -- If Deposit, the amount will be added to the selected account * -- If Withdraw, the amount will be subtracted from the account * --- Withdraws can only be an interval of 20 * ---- If you try to withdraw anything other number that is not in an * interval of 20 a message will appear Informing the user * --- If you do not have enough funds a message will appear * informing the user, they do not have enough funds * --- The program will count the number of times withdrawal and will display * a message when it reaches 4 informing the user they used their last free * withdraw * ---- The program will display a message at 5 withdraws and deduct $1.50 * from the account and will continue for any more withdraws * ----- If withdraw and charge makes account balance below 0 an * insufficient funds message appears and stops the withdraw * (ex: 5th withdraw is for $20 and you have $20 left the charge is added * to the withdraw causing you to have -$1.50 the program sees this and denies * the withdraw) * -- If Transferred, the selected account will receive * the amount from the other account * - In the output log, it will keep track of everything the program * does for bank records, this is to make sure the program is working properly */ import import import import import javax.swing.*;
