Implementing the Method

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.

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

  //constructors
  . . . .

  // methods
  int getBalance()
  {
     return  ;
  }

}

All getBalance() needs is a statement that returns the balance of the checking account.
