我正在做一个地址簿作为学校作业的一部分，我主要是想通了，但我被困在一个部分。这是我的代码第一。我有一个AddressBook类，它包含变量和适当的getter和setter方法来更改/返回书中每个人的信息。然后我有一个TestAddressBook类，它具有一个方法main来演示地址簿的工作方式。我坚持的唯一的事情就是最终的要求，我被要求比较两个名字，看看他们是否平等并打印结果。我按照我想要的方式设计程序，但由于某些原因，当我进行比较时，它不会打印比较结果。它根本不打印任何东西。我必须失去一些明显的东西。这是类的代码。地址簿程序

此外，只是为了清楚的是，该任务明确指出，我的AddressBook类中的compareNames方法不打印任何内容，它只是返回比较值。所以我必须从我的测试类中的方法调用打印它。即类似“名称1和名称1不相同的名称” – ripp2k
你知道你不是要在你的代码中打印'compareNames'的结果吗？ – UnholySheep
那么，如何才能在我的测试类中打印名称比较的结果呢？ – ripp2k
