annotation inheritance

I. Annotations annotation annotation is an annotation-like mechanism that adds annotations to your code to be used at a later time. Unlike annotations, annotations are for us, the Java virtual machines are not compiled, annotations are not compiled, but we can read the information in the annotations through the reflection mechanism. Annotations Use the keyword @

the parent class and acts as an assertion. If we use this annotation in a method that does not overwrite the parent class method, the Java compiler will alert with a compilation error.This annotaton often adds a supportability validation process when we try to overwrite the parent method and write the wrong method name.2,@DeprecatedDeprecated is also a kind of marker annotation. When a type or a member of

First recognized custom Annotation (annotation), first recognized Annotation When I was learning Java, I had been familiar with the concept of annotation for a long time. When the Child class describes the parent class method, I should add a line "@ Override" before the method. However, this

The PowerShell annotation character is divided into row and block annotation characters. A line annotation uses the pound sign (#) to cause a row, and a block annotation uses " Line annotation Character Examples are as follows: Copy Code code as follows: # d

Basic explanation of JavaScript inheritance (prototype chain, borrow constructor, hybrid mode, original type inheritance, parasitic inheritance, and parasitic combined inheritance) and javascript Constructor It's a long time to explain JavaScript inheritance. If you don't ta

Agreed to explain the JavaScript inheritance, but delayed to now explain. No more nonsense, go straight to the point.

Public, private, and protected are common inheritance methods. 1. Public inheritance) Public inheritance is characterized by the original state of both the public members of the base class and the protected members as the members of the derived class, while the private members of the base class are still private, it cannot be accessed by the subclass of this
