And then the front object-oriented ~ today is about the string class: In fact, the string class also contains a lot of object-oriented knowledge ~First of all, ask a question: we in the development process, if you want to use a class, it is necessary to create objects, this sentence is no problem ~ ~ in the actual development of the time is really this, only to c

as parent and child, animals and tigers, plants and flowers.The code generated by ROSE is as follows:# Include "C11.h" Class C12: public C11 ...{ }; 5. Template Here, by the way, the template The code for the above figure is as follows:Template Class C13 ...{ }; Let's talk about the degree of repetition. In fact, a

Principle: Java reflection is able to get the name of a property and then invoke a method of the class by invoking it.For example, there is a property called username, this class has written a method called GetUserName, Invoke call GetUserName this method. The code is as follows Copy

Public B () {System.out.println ("Create B");} Class A extends B { static {System.out.println ("Load A");} Public A () { System.out.println ("Create A");} public class Test { public static void Main (string[] args) { A A = new A (); } The answer is Load b-->load a-->create b-->create A;The reason is a sentence: the first father, will have a son! When the program runs, load AB two classes, because

extension above. For example, if A and B have A "one-to-many" repetition degree, there is A list in A that stores N references of object B, that's all. Now, I have finished the class graph relationship above. I hope you will get something better. I have also spent a lot of time (drawing, generating code, writing to BLOG, alas, a sweat ). However, it is worth it if you can thoroughly understand the relation

description, we should be clear about the relationship between the various relations and what the code is like, the so-called degree of repetition, it is just an extension above. For example, if a and B have a "one-to-many" repetition degree, there is a list in a that stores n references of object B, that's all. Now, I have finished the class graph relationship above. I hope you will get something better.

Objectiveclass diagrams and sequence diagrams are two of the most commonly used diagram in UML. I will make a detailed summary. In many books, or Web sites, when introducing the design of a subsystem of a system, many times, a simple class diagram is given to describe the relationship between the classes that make up the subsystem. This is sufficient to illustrat
