Java™ How To Program (Early Objects), Tenth Edition

3.5.2 AccountTest Class to Use Class Account

Class AccountTest (Fig. 3.9) creates two Account objects (lines 9–10) and initializes them with a valid balance of 50.00 and an invalid balance of -7.53, respectively—for the purpose of our examples, we assume that balances must be greater than or equal to zero. The calls to method System.out.printf in lines 13–16 output the account names and balances, which are obtained by calling each Account’s getName and getBalance methods.
