i.

Print receipt if requested

ii.

I have two classes and I am trying to get the pin number and the account number to match but I am having trouble. Here is the code.

import javax.swing.*; import java.io.*; import java.util.*; import java.lang.*; public class ATMu { public static void main (String[]args) throws IOException { JOptionPane.showMessageDialog(null,"Welcome"); for (int i=0;i<3;i++) { String ACCT = JOptionPane.showInputDialog(null,"Enter Account Number"); int AP=Integer.parseInt(ACCT); Account_info A1=new Account_info(AP); if(AP==A1.TestAcct()) { i=2; } else { JOptionPane.showMessageDialog(null,"Wrong Acount Number"); } if(AP==A1.TestAcct()) { for(i=0;i<3;i++) { String PIN=JOptionPane.showInputDialog(null,"Enter PIN Number"); int num=Integer.parseInt(PIN); Account_info A2=new Account_info(num); System.out.println(A1.Aind()+" "+A2.Pind()); if(num==A2.TestPin()&& A1.Aind()==A2.Pind()) { i=2; } else { JOptionPane.showMessageDialog(null,"Wrong PIN"); }

} } } } }
