java multithreading - lambda arguments

public class hh {

public static void main(String[]args)
{
    ilike like =(a)->{
        System.out.println("ad"+a);
    };

    like.lambda(2);
    **只带有一个参数可以简化为:**
    ilke like =a->{
    System.out.println("ad"+a);
};

With only one line of code parameters and simplified to:

ilke like =a->System.out.println("ad"+a);

}

}
interface ilike{

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

public void lambda(int a)
{
    System.out.println("i like"+"-->"+a);
}
}
