java是否支持像c＃这样的显式接口实现？ [英] Does java support explicit interface implementation like c#?

问题描述

我试过这样做：

interface pet {
    void sleep();
}
interface robot {
    void sleep();
}

public class roboGarfield implements pet , robot {

    /*
     * this gives error
    void pet.sleep(){

    }
    */

    @Override
    public void sleep() { System.out.println("this isn't really specific.."); }

    public static void main(String[] args){
        roboGarfield t = new roboGarfield();
        t.sleep();
        ((pet)t).sleep(); // similar to C# 
        ((robot)t).sleep();
    }    
}

但即使我可以投出 roboGarfeild 对象 pet 或机器人类型，我不能显式实现，如c＃。

But even though i can cast the roboGarfeild object to its pet or robot type , i cant do an explicit implementation like c#.

我做错了什么？或者只是在java中不支持？

Anything i'm doing wrong ? or is it just not supported in java ?

编辑：因此，java不支持像C＃这样的显式接口实现。但是对于无法避免的情况，Holger的委托方法似乎就好了。

So , java doesn't support explicit interface implementation like C#. But for cases where they can't be avoided , Holger's delegate method seems like the way out.

感谢所有回复。

推荐答案

public class roboGarfield implements pet , robot {

     @ovveride
     public void  sleep(){
         //here you are implementing sleep method
         //But satisfying both pet and robot interface's sleep method.
     }

执行此操作时，在java中，单个实现适用于接口。 AFAIK， NO 解决。

When you do this , in java the single implementation works for the both interface. AFAIK, NO work around.
