我自己的测试内部类笔记

public class TestInnerClass {
    public static void main(String[] args) {
        System.out.println("测试成员内部类");
        // 测试成员内部类
        Outer outer = new Outer(0);
        outer.privateInnerGetI();
        Outer.PublicInner publicInner = outer.new PublicInner();
        publicInner.printI();
        System.out.println("测试局部内部类");
        // 局部内部类
        final int i = 0;
        class A{
            public void print(){
                System.out.println("AAA,i = "+i);
            }
        }
        A a = new A();
        a.print();
        System.out.println("测试匿名内部类");
        // 测试匿名内部类
        Runnable runnable = new Runnable() {    
            @Override
            public void run() {
                // TODO Auto-generated method stub
                
            }
        };
        Thread[] threads = new Thread[10];
        for(int j = 0;j<10;j++){
            threads[j] = new Thread(runnable);
        }    
        System.out.println("测试静态内部类");
        // 测试静态内部类
        Outer.staticInner os = new Outer.staticInner();
        os.notStaticPrint();
        Outer.staticInner.staticPrint();
        
    }

    
}
// 成员内部类
class Outer{
    private int i;
    public Outer(int id){
        this.i = i;
    }
    public void privateInnerGetI(){
        new PrivateInner().printI();
    }
    
    class PublicInner{
        private int i = 2;
        public void printI(){
            System.out.println(i);
        }
    }
    class PrivateInner{
        public void printI(){
            System.out.println(i);
        }
    }
    
    // 测试静态内部类
        private static final int m = 1;
        static class staticInner{
            public void notStaticPrint(){
                System.out.println("Outer.staticInner.notStaticPrint(),m = "+m);
            }
            public static void staticPrint(){
                System.out.println("Outer.staticInner.staticPrint()");
            }
        }
    
}
