One: Functional interface1. The concept of a functional interface is that this interface must have only one abstract method, which can be displayed by @functionalinterface (similar to @override), but an interface with no such annotations but only one abstract method is also a functional interface ; (Interfaces also hav
The base class baseoutput explicitly inherits an interface ioutput, and the class trackoutput inherits baseoutput, and also inherits the ioutput interface. Assume that ioutput has a method output, so there are two output methods in trackoutput, one source is the base class baseoutput and the other source is the interface ioutput. This leads to confusion. What sho

The base class Baseoutput explicitly inherits an interface Ioutput, after which the class Trackoutput inherits Baseoutput, and the Ioutput interface is inherited at the same time. Suppose Ioutput has a method output, so there are two output methods in Trackoutput, one from the base class Baseoutput, and one originating from the interface ioutput. This has led to
(i) Collection framework: The Java language designer has made some specifications (interfaces) and implementations (classes that implement interfaces) for commonly used data structures and algorithms. All abstract data structures and operations (algorithms) are collectively referred to as the collection framework.Programmers in the application, do not have to consider the data structure and algorithm implementation details, only need to create some objects with these classes, and then directly

IntroductionInterface is a very important element in object-oriented programming language, it is described as a set of services, for the client, we are only concerned about the services provided, but not the implementation of the service, for the service-side class, if it wants to implement a service, to implement the interface associated with the service, It also does not have to interact with clients that use the service too much. This good design m
Objective:When we define the members of an interface, we do not need to write the access control, because it is the default public and can only be public. When a class is to implement this interface, it is natural to expose its members. I've been doing this for a long time.Interface Interface1 { string GetName (string name); }Class Class1:interface1 {public string GetName (string name
hard Disk Interface
The current hard disk interface type is not much, mainly IDE, SCSI, SATA three kinds. Many times the IDE replaces the Ultra ATA, many people are accustomed to the Ultra ATA hard disk is called IDE hard disk, but need to explain that the concept of the IDE is greater than ata--in principle all hard drive integrated controller design belongs to IDE,SCSI is no exception. Of course, with
All can;one interface can inherit another interface? Interface inheritance Interface The essence is that an abstract class inherits another abstract class (an instance of which neither method is written). When a class inherits an abstract class, it must override the abstract method in the parent abstract class, and if
