方法一：
Socket socket=null
try{
ServerSocket serversocket=nwe ServerSocket(8080)
while(true){
socket=serversocket.apccet();
new ServerThread(socket).start();
}
}catch(IOException e){
e.printStackTrace()
}
方法二：
public class ServerThread extends Thread{
private Socket socket;
public ServerSocket(socket){
this.socket=socket;
}
public void run(){
//复写run方法
InputStream is=null;
OutputStream os=null;
String ip=socket.getLocalAddress().getHostAddress();
String port=socket.getPort();
try{
while(true){
in=socket.getInputStream();
byte[] buffer=new byte[1024];
int index=in.read(buffer);
String receive=new String(buffer,0,index);
System.out.println ("接受到服务器的内容是"+receive);
if(recive=="exit") break;
out=sokect.getOutputStream();
String mes="word";
out.write(mes.getBytes());
System.out.println ("向服务器发送的内容："+receive);
}
in.close();
out.close();
socket.close();
}catch(IOException){
e.printStackTrace();
}
}
}
