今天看了黑马的视频。有个例子按照视频做的。提示这个错误。谁能帮忙看看。下边是源码。

System.out.println(ip+"::"+data);

}
}

class ChatDemo
{
public static void main(String[] args) throws Exception
{
DatagramSocket sendSocket = new DatagramSocket();
DatagramSocket receSocket = new DatagramSocket(10000);

new Thread(new Send(sendSocket)).start();
new Thread(new Send(receSocket)).start();
}
}

String data = new String(dp.getData(),dp.getLength());  方法已过时

对于过时对象，是不一推荐使用的，但时对于一些老的程序中可能使用了，所以java会将标为过时。

已经解决了。当时误以为是没有编译成功。后发现只是个善意的提示而已。呵呵
