关于聊天程序，代码编译不成功的问题
import java.io.*;

class Send implements Runnable
{
private DatagramSocket ds;
public Send(DatagramSocket ds)
{
this.ds = ds;
}
public void run()
{
try
{

}

new Thread(new Send(sendSocket)).atart();
new Thread(new Rece(receSocket)).start();

}
错误提示如下：
:\javalianxi>javac 1605.java
605.java:23: 需要 ')'

ngth,InetAddress.getByName(192.168.1.254),10002);

错误
就这么一句代码怎么这么多错误，求解答！

DatagramPacket dp = new DatagramPacket(buf,buf
ngth,InetAddress.getByName(
192.168.1.254
),10002);
加粗部分的Ip地址加个引号即可，
这个方法接收的是一个字符串：getByName(String str),
还有你那异常输出语句应该是 System.out.println("接收失败");
而你多加了一个p System.pout.println("接收失败");

这回差不多咯~

代码可以放进代码区，这样阅读起来更方便
