先来复习一下,Java 内部类一共分为四种:成员内部类、静态内部类、局部内部类、匿名内部类。其中,前两者应用较多,所以我着重介绍前两种。 成员内部类 形如(可以没有继承): public class Outter extends FatherA { public class Inner extends FatherB { } } 内部成员类的主要特性: 内部类实例的创建依赖外部类...
Java 的 inner class 是一种在一个类中定义另一个类的结构,这种嵌套的类提供了一种在逻辑上组织相关类的方式,同时它们能够访问外围类的成员,包括私有成员。在 Java 中,inner class 的设计不仅是为了代码的结构性,还为了增强封装性和可维护性。接下来,我们深入探讨 inner class 的技术原理,使用场景,并结合 JVM ...
makes explicit the transformation that in Java was implicit. We give the inner class a reference to the outer class (here, we called ito_) and pass it as an explicit parameter to the inner class’s constructor. And when we want to access a member of that outer class, we useo_to do...

And to create an object of static nested class you don't need the static nested class to have a reference to the outer class object. Static nested class is the simplest form of nested class. A static nested class is declared with the static modifier. When a static nested class is nested...
InheritInner.java 可以看到,InheritInner只继承自内部类,而不是外围类。但是当要生成一个构造器时,默认的构造器并不算好,而且不能只是传递一个指向外围类对象的引用。 此外必须在构造器内使用如下语法: enclosingClassReference.super( ); 这样才提供了必要的引用,然后程序才能编译通过。
