Component design requires adherence to
Definition: A software entity, such as a class, module, or function, should be open to extensions and closed to modifications.
Problem:During the software life cycle, errors may be introduced to the Old Code when the original code of the software needs to be modified due to changes, upgrades, maintenance, and other reasons, it may also cause us to have to refactor the entire function and re-test the original code.
Solution:When the software needs to change, try to implement changes by extending
In object-oriented design, how to deal with changes in design requirements through small changes is a matter of great concern to designers. To this end, many oo pioneers have proposed many object-oriented design principles to guide the design and development of OO. Below are

But everything has degrees, although can avoid and non-direct class communication, but to communicate, will inevitably through an "intermediary" to contact, such as in this case, the head office is through the
The basis of reusable object-oriented software-design mode, with its reusable design intention, ingenious logical thinking by the vast number of object-oriented program design is sought after. But many programmers often turn the question of thinking into what patterns they encounter. This kind of confucianism、the thinking has seriously influenced the artistry of
