8、多线程：Lamda表达式

lamda表达式推导过程：

* 推导lamda表达式
* */
public class TestLamda {

    //3、静态内部类
    static class Like2 implements ILike{

        @Override
        public void lamda() {
            System.out.println("I like lamda2");
        }
    }


    public static void main(String[] args) {
        ILike like = new Like();
        like.lamda();

        ILike like2 = new Like2();
        like2.lamda();


        //4、局部内部类
        class Like3 implements ILike{

            @Override
            public void lamda() {
                System.out.println("I like lamda3");
            }
        }
        ILike like3 = new Like3();
        like3.lamda();

        //5、匿名内部类，没有类的名称，必须借助接口或者父类
        ILike like4 = new ILike() {
            @Override
            public void lamda() {
                System.out.println("I like lamda4");
            }
        };
        like4.lamda();


        //6、lamda简化
        ILike like5 = ()->{
            System.out.println("I like lamda5");
        };
        like5.lamda();
    }

}

//1、定义一个接口类，接口类里面只有唯一一个抽象方法
interface ILike{
    void lamda();
}

//2、实现类
class Like implements ILike{

    @Override
    public void lamda() {
        System.out.println("I like lamda");
    }
}

输出结果
