Dynamic Method Dispatch with Code Example in Java Example Code: classShape{Shape(){}voiddisplay(){System.out.println("I am in the Shape class");}}classRectangleextendsShape{Rectangle(){}voiddisplay(){System.out.println("I am in the Rectangle class");}}classTriangleextendsShape{Triangle(){}...
In this post, we will about Dynamic method dispatch which is also referred as run time polymorphism.
如果用户输入小轿车,就执行小轿车的驾驶方法, 涉及到用户,这些都只能在运行时才能干。运行时的,就是动态的,所以这也是动态方法调度(dynamic method dispatch), 既然是父类指针指向子类,这也是向上转型Upcasting(为什么是向上?看我本章的第一张图:父类 fuLei=(父类)new 子类(); ,,,感觉到一种向上转型的意味吗?
Dynamic Method Dispatch in Java This mechanism known as method overriding and it’s one of the way that supports Runtime Polymorphism. This features worked on run time and the behaviour of this work as overridden method i.e. if any class extended and both have same method then each class ...

you can approximate such a language feature by overriding a method in a subclass. Thanks to Java’sdynamic method dispatch, this allows you to inject any framework functionality into user code by creating a subclass at runtime. And conveniently, you can invoke the user’s method by simply cal...

The DDI further supports loading additional dex classes into a process. This enables instrumentation code to be partially written in Java and thus simplifies interacting with the instrumented process and the Android framework. The toolkit is based on ADBI (see below) and consists of one main librar...

This way works well when configuring routing using controller fields - Irked uses Java reflection to read the order the fields are defined in the source code and configure the handlers in the correct order taking, advantage of implicit Vert.x-web route order - but this naive "definition order...
