Explanation / Answer

//The code in bold is added to use enum in this Program

enum AccountEnum{Savings, Checking, Business, CreditCard;}

public class MyClass {
public static void main(String args[]) {

Account savings = new Account(101,"10001",500.00);
Account checking = new Account(102,"10001",700.00,"1122");
Account business = new Account(103,"10001",900.00,"AA","A01");
Account credit = new Account("10001","112233",500.00,1000.00);

System.out.println(checking.toString());
