In Java,dynamic binding is the default behaviore and you don't need to remember to add any extra keywords (C++ uses virtual keyword) in order to get polymorphism. upcasting(向上转型)-- the process of treating a derived type as though it were its base type The name "cast" is used in ...

Popular frameworks for web development include Spring and Apache Struts. Additionally, this language can be used to create dynamic web pages and handle server-side processing. While other languages are often used for front-end development, Java plays a significant role in building the server-side ...
Interchangeable objects with polymorphism 多态允许我们不必依赖特定的类型来写代码。以前面讲述过的"形状"为例,方法操纵一般的图形而不用考虑它们是圆形、正方形、三角形还是其他的一些从未定义过的形状。所有图形能被画、擦除、移动(drawn, erased, and moved),这些方法简单的发送信息给一个shape object,它们不用考...
to Java technology-based applications, in which the methods of remote Java objects can be invoked from other Java virtual machines, possibly on different hosts. RMI uses object serialization to marshal and unmarshal parameters and does not truncate types, supporting true object-oriented polymorphism. ...
It is possible because of Java polymorphism, described in Chapter 2, Java Language Basics. For example, if a SomeClass class extends SomeBaseClass, both of the following declarations and initializations are possible:SomeBaseClass someBaseClass = new SomeBaseClass();someBaseClass = new SomeClass(...
In order to understand the Visitor pattern, we need first to digest double dispatch. What is double dispatch? Java and many other languages support polymorphism (many shapes) via a technique known as dynamic dispatch, in which a message is mapped to a specific sequence of code at run...
