java多线程-lambda带返回值

public class hh {

public static void main(String[]args)
{
    ilike like=(a,b)->{ 
        System.out.println("ad"+(a+b));
        return a+b;
    };
    like.lambda(100, 200);
    //一行代码省略格式
    ilike like2=(a,b)->a+b;//return 也省略掉
    like2.lambda(200, 200);

    ilike like3=(a,b)->100;//相当于返回值就是100
    like3.lambda(300, 200);
}

}
interface ilike{

int lambda(int a,int b);
}
class like implements ilike{

public int lambda(int a,int b)
{
    System.out.println("ad"+(a+b));
    return a+b;
}
}
