This design's weakness should be apparent: add() doesn't check the type of the provided object, and so exportAll() takes a grave risk in so blithely calling export().
这种设计的缺点显而易见：add()不检查所提供对象的类型，所以exportAll()在轻快地调用export() 时冒了致命的风险。
Once the message has been sent, the sender can store a reference to the Future object and check periodically for completion, or it can block and wait if needed by calling the get method.
消息被发送之后，发送者可以保存对Future对象的一个引用并定期检查是否完成，或者，它也可以通过调用get方法来阻塞和等待。
That is, we no longer check that the final balance of the test account is correct; we would check that function in the unit test for the Transaction object, not the AtmGui object.
也就是说，我们不再检查测试帐户的最终余额是否正确；我们将在对Transaction对象的单元测试中检查该函数，而不是在对atmgui对象的单元测试中。
Next, check the percentage of the CPU consumed by using the Date object.
下面，检查使用Date对象消耗的cpu百分比。
