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 ...
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...
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...
To access the inner class, create an object of the outer class, and then create an object of the inner class:ExampleGet your own Java Server class OuterClass { int x = 10; class InnerClass { int y = 5; } } public class Main { public static void main(String[] args) { OuterClass...
Here's an example of how you can declare inner classes in Java. Example 1: Inner class classCPU{doubleprice;// nested classclassProcessor{// members of nested classdoublecores; String manufacturer;doublegetCache(){return4.3; } }// nested protected classprotectedclassRAM{// members of protected...
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...
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...
