内部类

普通内部类的创建写法

public class TestInnerClass{
    class InnerClass{
        private String name;
        public void show(){
            System.out.println("show");
        }
    }

    public static void main(String[] args){
        InnerClass InnerClass = new StaticClass().new InnerClass();
    }
}

静态内部类的创建写法

public class TestInnerClass{
    static class InnerClass{
        private String name;
        public void show(){
            System.out.println("show");
        }
    }

    public static void main(String[] args){
        InnerClass InnerClass = new StaticClass.InnerClass();
    }
}

方法内部类的写法，需要在方法内new这个内部类

public class MethodInnerClass{
    public void show(){
        System.out.println("show");
        class InnerClass{
            private String name;
            public void show(){
                System.out.println("test");
            }
        }
        new InnerClass().test();
    }
    public static void main(String[] args){
        MethodInnerClass methodInnerClass = new MethodInnerClass();
        methodInnerClass.show();
    }
}
