求关于socket通信的小程序

[Eric1drifter]

那位兄台有关于socket的小程序，自己写的有注释的最好，不要太短啊，如果帮助很大的话我给50分
寥寥几分不成敬意，请大家不要吝惜源代码啊

public class Server

ServerSocket server;
DataOutputStream output;
Socket socket;
public Server (){
try{
// create a server on port 5000
server=new ServerSocket(4546);
// display interactive informaion
System.out.println("Server created.");
System.out.println("waiting for client to connect on...");
// waiting for client to connect on...
socket = server.accept();
// client connected
System.out.println("client connected.\nShutdown!");
output = new DataOutputStream(socket.getOutputStream());
output.writeUTF("Welcome to Server.Bye!");
