The merging Reuse Principle is also known as the composition/aggregate Reuse Principle and carp principle. Its definition is as follows: Composite Reuse Principle (CRP): Use object combinations as much as possible instead of inheritance to achieve reuse. The merging Reuse Principle is to use some existing objects in a new object through the association relationship (including the combination

/20071205214949530.html of interface segregation principle (ISP)-OO design, we introduce a class-oriented design principle: Clients shocould not be forced to depend upon interfaces that they do not use. users cannot be forced to rely on interfaces they do not use. Applying this concept to a wider range of packages is the basic concept of CRP: do not combine cla

that the structure of the program is starting to become loose. Any change to the input or output device will force you to re-organize the condition judgment of the while loop. But after all, your program can work normally. But now you have reached the bottom line. If a hateful customer breaks your design by changing the demand, you will leave immediately. You made up your mind. Your crash ...... Unfortunately, it didn't take two weeks. You did

can manipulate an abstract body, in which the module relies on a fixed abstract body, so it can be closed for modification, and through this abstract derivation, it can also extend the behavior of this module.Developers should abstract only those parts of the program that exhibit frequent changes, rejecting immature abstractions and abstractions as important as themselves.The Richter replacement principle:Its subclass object can be substituted for th

30-minute understanding of Object-Oriented Design Principles Many people have read the design patterns, but Martin does not have much estimation on the object-oriented

1. Opening and closing principle (the Open Closed principle OCP) A module should be open in terms of extensibility and should be closed in terms of modification. Therefore, the interface encapsulation mechanism, abstract mechanism and polymorphic technique should be considered as far as possible in object-oriented design. The principle is also suitable for non

The object-oriented design principle is the core of OOPS (object-oriented programming system, Object-Oriented Programming System) programming. However, most Java programmers pursue
