Java实现多继承

偶然看到的，觉得挺好

转自java实现多继承

class Call {  
    public void callSomebody(String phoneNum){  
        System.out.println("我在打电话喔，呼叫的号码是：" + phoneNum);  
    }  
} 

class SendMessage {  
    public void sendToSomebody(String phoneNum){  
        System.out.println("我在发短信喔，发送给 ：" + phoneNum);  
    }  
}  

实现

public class Phone {  
    private class MyCall extends Call{  
          
    }  
    private class MySendMessage extends SendMessage{  
          
    }  
      
    private MyCall call = new MyCall();  
    private MySendMessage send = new MySendMessage();  
      
    public void phoneCall(String phoneNum){  
        call.callSomebody(phoneNum);  
    }  
      
    public void phoneSend(String phoneNum){  
        send.sendToSomebody(phoneNum);  
    }  
      
    public static void main(String[] args) {  
        Phone phone = new Phone();  
        phone.phoneCall("110");  
        phone.phoneSend("119");  
    }  
}  

其实就是使用了代理模式
