int currentBalance()

Implementing the Current Balance Method

class CheckingAccount
{
  // instance variables
  String accountNumber;
  String accountHolder;
  int    balance;

  //constructors
  . . . .

  // methods
  int currentBalance()
  {
     return________________
  }

}

The method returns the current balance, which is an int so the return type is "int". The method does not need any input data, so its parameter list is empty. You still need to have the two parentheses ( ) even though there is nothing inside of them. So far, the class looks like this:

All you need to put in currentBalance() is a statement that returns the balance of the checking account.
