如何实现socket的长连接

现编这个就是个多线程服务器，只要在client不释放连接，服务器端的run里边写while（TRUE）循环，那么就可以长期连接。class ConnectionThread extends Thread{Socket clientint counterpublic ConnectionThread(Socket cl，int c){client = clcounter= c}@Overridepublic void run(){try{String destIP=client.getInetAddress().toString()

int destport =client.getPort()

PrintStream outstream=new PrintStream(client.getOutputStream())

DataInputStream instream=new DataInputStream(client.getInputStream())

String inline=instream.readLine()}//trycatch(IOException e){System.out.println(e)}}//run
