Java有嵌套类(Nested Classes)和内部类(Inner Classes)的概念。 嵌套类(Nested Classes)分为两种:static and non-static。即静态的和非静态的,静态的嵌套类我们称之静态嵌套类(static nested classes),非静态的嵌套类我们称之为内部类(inner classes)。 静态的嵌套类我们能够这样表示: OuterClass.StaticNestedClass ...
A non-static nested class is a class within another class. It has access to members of the enclosing class (outer class). It is commonly known asinner class. Since theinner classexists within the outer class, you must instantiate the outer class first, in order to instantiate the inner cl...
2.在外面引用Static Nested Class类的名称为“外部类名.内部类名”。 3.在外面不需要创建外部类的实例对象,就可以直接创建Static Nested Class,例如,假设Inner是定义在Outer类中的Static Nested Class,那么可以使用如下语句创建Inner类: Outer.Inner inner = new Outer.Inner(); 4.由于static Nested Class不依赖于...
Nested Class (一般是C++的说法),Inner Class (一般是JAVA的说法)。Java内部类与C++嵌套类最大的不同就在于是否有指向外部的引用上。 注: 静态内部类(Inner Class)意味着 1 创建一个static内部类的对象,不需要一个外部类对象 2 不能从一个static内部类的一个对象访问一个外部类对象 Anonymous Inner Class (匿...
In Java, it is also possible to nest classes (a class within a class). The purpose of nested classes is to group classes that belong together, which makes your code more readable and maintainable.To access the inner class, create an object of the outer class, and then create an object ...
class TestCry { public static void main(String[] args) { Cry p = new Cry(); Fool c = p.laugh(); Acumen d = p.comeOn("Lake_xie"); } } 說明:先有Cry再來Fool和Acumen因為非靜態的; 好處多多:內部類對象可以訪問創建它的外部類對象的內容-也包括變量(公私都可以),不過還前提,內部類對象必須...
class InnerClass { OuterClass o_; public InnerClass(OuterClass o) { o_ = o; } public string GetOuterString() { return o_.s; } } void SomeFunction() { InnerClass i = new InnerClass(this); i.GetOuterString(); } } In Java, the inner class has a secretthis$0member which remembe...
