ATM System

Problem: Create a program for a BANK called ATM SYSTEM

Transactions are:

- Balance Inquiry
- Withdraw
- Change Pin

NOTE: 

1.)  There will be 5 account holders
        - Name
        - Pin

2.) Ask for a transaction

3.) Perform the transaction

4.) Ask another transaction (Y/N) if  "Y" loop again

Code: 

package atm;
import java.util.Scanner;
public class Atm {
static Scanner candy = new Scanner (System.in);
public static void main(String[] args){

String name[] = {"Hatake Kakashi", "Uzumaki Naruto", "Oborume Shino", "Nara Shikamaru","Uchicha Sasuke"}; 
int pin[] = {1111, 2222, 3333, 4444, 5555}; 
double withdrawAmount, balance[]={10000.00,20000.00,50000.00,100000.00,1000000.00};
int account, results, choice, cpin = 0, oldpin = 0, newpin = 0;
String answer;
char choice1;


System.out.println("---AUTOMATED TELLER MACHINE---");
System.out.println("Enter your PIN number: ");
account =candy.nextInt();
results = pin (pin,account);
if(results==-1){
System.out.println("Invalid");
}

System.out.println("\n---[ WELCOME " + name[results]+"! ]---\n"); 
System.out.println(" -- TRANSACTION -- ");

}

System.out.println("\n Withdrawal Successful");
System.out.println("\n Your Balance is: " +balance[results]);
}break;

case 3: System.out.println("Enter Old Pin:\t\t");

System.out.println("Enter New Pin:\t\t");

System.out.println("Confirm New Pin:\t");

pin[results]=cpin;
System.out.println("\n PIN Changed");
} break;

}


System.out.println("*****************************");
System.out.println("You want another transaction?");

}

System.out.println("THANK YOU && COME AGAIN !!");
}

private static int pin(int[] pin, int account) {
for( int x=0; x<pin.length; x++){
if (account == pin[x]){
return x;
 }
   } return -1;
