A few days ago in the left to fly voice, inadvertently realized that the interface in Java and JS commonly used callback function a bit similar, today here to tidy up ideas.Interface,java in the interface, why there is this thing.One, reservation statementFor example, two programmers a and b,a to write a program, which need to call the program written in B. At this point a can write an interface:public
Comparablecomparable is the sort interface.If a class implements the comparable interface, it means "this class supports sorting." The class that implements the comparable interface supports sorting, assuming that there is now a list (or array) of objects for the class that implements the comparable interface, the list (or array) can be passed through Collections

In object culture, class inheritance is a very powerful mechanism, and a more powerful Inheritance Mechanism should be inherited from an interface.In this article, we will discuss the features of interfaces.First, the interface is defined in a similar way as a class. The difference is that a class represents an entity, and an

Why use abstract classes:
If the subclass is not correctly rewritten, no prompt is displayed.
Assume that the code of the parent class is as follows:

The code in the subclass is as follows: rewrite the method in the parent class

The way you use the interface is not as difficult as you might think.For example, if the provided interface is a get form, the address is output directly on the Web page, and the parameters are pieced together to get the return value.If it is a post

Interfaces InterfaceIn software engineering, it is very common to define how software from different development groups interact with each other in a "contract. Each group can develop its own code independently without knowing the code of another group. The interface in Java is such a "con
The following rules outline the interface naming rules:
Use nouns, noun phrases, or adjectives describing behavior to name interfaces. For example, the interface name icomponent uses a descriptive term. The Interface Name icustomattributeprovider uses a noun phrase. The name ipersistable uses an adjective.
Use Pascal case.
Avoid abbreviations.

Interface (interface) is another important technique provided by Java, which is very similar in structure to abstract classes and has data members and abstract methods, but it differs from the abstract class in the following two points:1, the data members in the interface must be initialized, and the data members are constants.2. The methods in the
