静态内部类

静态内部类

示例代码

public class Outer {
    private String name = "qiudajiang";

   static class Inner{
        private int age = 21;
        private String name = "qiudashuai";
        private static String address = "xxx";
        void show(){
            //访问外部类的属性要先创建外部类对象
            Outer outer = new Outer();
            System.out.println(outer.name);
            //静态内部类访问静态内部属性通过类名访问
            System.out.println(Inner.address);
            System.out.println(name);
            System.out.println(age);
        }
    }
}

测试代码

public class OuterTest {
    public static void main(String[] args) {
        //Outer outer = new Outer();
        //Outer.Inner inner = outer.new Inner();
        //inner.show();
        Outer.Inner inner = new Outer.Inner();
        inner.show();
    }
}
