abstract tapestry

Looking at work today, the code suddenly has the following ideas:/** * Created by ZQ on 2017/5/25. * Abstract Classes */public abstract class ABSTRACTC {public void C () { D (); System.out.println ("C_1"); E (); } public abstract void D ();// {// System.out.println ("c_1"),// } public

C + + is a multi-paradigm language, so C + + is difficult to learn, so C + + powerful, comparable to java,c#, with C + + to do software development, development cycle is much longer.Why is it? This is because C + + has a high degree of freedom, in other words, the more liberal language, the longer the period of software development, there is a certain reasonDegrees of freedom are not easy to control, Java and C # their libraries are very powerful, which limits the degree of freedom to a certain

All right, the parent class postparent is defined as abstract, which specifies that the subclass must re-implement the Buildhtml () method, which does not have curly braces, and if there are any content will be an error. Now the more you see the code is not necessary to use abstract class, with inheritance is also very chicken, well, there is nothing to say as if ... In addition i separate MySQL outside, so

An interface is a special abstract class, which is usually used by inheritance. Why design abstract classes? For inheritance, common classes can also be used for inheritance. However, in reality, there are some classes that do not make sense to instantiate them. For example, animal, we do not instantiate an animal object, but instantiate a specific animal object such as bird and tiger. In this way, some m

Why the abstract factory model? In the factory model, a specific factory class is responsible for creating a separate product. If there are two different products, two different factory classes are required, even if the two products have some necessary relationships. Therefore, the abstract factory model should be used for multiple series products. The factory model is a product and a factory, and the seco
