1, note that the code should use the grammatical elements required in the topic;
2, pay attention to good code style;
3, attention to submit the entire project, upload compressed attachments, mutual evaluation can be successfully executed;
4, pay attention to write a brief code description (please explain the use of the IDE, etc.);

Write a small program that defines interfaces, classes, abstract classes, define their members (fields and methods), and requires the use of Setter/getter, static, final, abstract, @Override, and other grammatical elements, and write a main function to use them. These classes, interfaces can be around one of the following topics

The topic is: Flying the world: to a flight relay (that is, a number of objects can be flown in turn call);
