lambda实现

public class TestLambda1 {
    //3.静态内部类
    static class Like2   implements ILike{
        @Override
        public void lambda() {
            System.out.println("I like lambda2");
        }
    }
    public static void main(String[] args) {
        ILike like = new Like();
        like.lambda();
        like = new Like2();
        like.lambda();
        //4.局部内部类
        class Like3 implements ILike {
            @Override
            public void lambda() {
                System.out.println("I like lambda3");
            }
        }
        like = new Like3();
        like.lambda();
        //4.匿名内部类,没有类的名称，必须借助接口和父类
        like = new ILike() {
            @Override
            public void lambda() {
                System.out.println("I like lambda4");
            }
        };
        like.lambda();
        //6.用lambda简化
        like = () -> {
            System.out.println("I like lambda5");
        };
        like.lambda();
    }
}
//1.定义一个函数式接口
interface ILike{
    void lambda();
}
//2.实现接口
class Like implements ILike{
    @Override
    public void lambda() {
        System.out.println("I like lambda1");
    }
}

public class TestLambda2 {
    public static void main(String[] args) {
        iLave lave = (String name) -> {
            System.out.println("我喜欢" + name);
        };
        lave.Lova("lsk");
        //1.简化参数类型 多个参数也可以去掉参数类型
        iLave lave2= ( name) -> {
            System.out.println("我喜欢" + name);
        };
        lave2.Lova("sss");
        //2.简化括号
        iLave lave3= name -> {
            System.out.println("我喜欢" + name);
        };
        lave3.Lova("www");
        //2.简化花括号 一行可以简化花括号
        iLave lave4= name -> System.out.println("我喜欢" + name);
        lave4.Lova("hua");
    }
}
interface iLave{
    void Lova(String name);
}
class love implements iLave{
    @Override
    public void Lova(String name) {
        System.out.println("我喜欢"+name);
    }
}
