package Lamada;

public class lamada {
//3.静态内部类;
   static class A2 implements bean{
        @Override
        public void shut() {
            System.out.println("I am lamada2");
        }
    }
        public static void main(String[] args) {
            bean like=new A();
            like.shut();
            like=new A2();
            like.shut();

//4.局部内部类
            class A3 implements bean{
                @Override
                public void shut() {
                    System.out.println("I am lamada3");
                }
            }

            like=new A3();
            like.shut();

//5.匿名内部类,没有类的名称,必须借助接口或者父类
            like=new bean() {
                @Override
                public void shut() {
                    System.out.println("I am lamada4");
                }
            };
            like.shut();
//6.用lamada表达式(jdk8)
           // like=()->{
               // System.out.println("I am lamada4");
            };
   //like.shut();
        }








}
//1.定义一个函数式接口
interface bean {
    void shut();
}
//2.实现类
 class A implements bean{
    @Override
    public void shut() {
        System.out.println("I am lamada");
    }
}
