1. Avoid the principle of repetition (Dry–don ' t repeat yourself)The most basic principle of programming is to avoid duplication. There are always many structures in the program code, such as loops, functions, classes, and so on. Once you repeat a statement or concept, it is easy to form an abstract body.2. Abstract principles (Abstraction Principle)Related to the dry principle. Keep in mind that every important feature in your program code can only appear in one place in the source code.3.

The quality of the interface directly affects the company's image, I guess some people will compare "good interface" with "gorgeous interface", "Bad interface" with "simple interface. Whether the interface is good or bad depends on whether it is gorgeous to a certain extent, but it is not absolute, but targeted.

The same, the event "Cancel task" occurs in the "Execute" state, you need to do a lot of work, such as recycling resources to perform tasks.In general, the assumption that states are very small may not involve the concept of state machines.But assume that the state, the event is very many. Assuming that the design is not good state machine, software development to the late will be very
