초간단! TCP 를 이용한 서버의 시간 알아오는 프로그램

TimeServer.java

import java.net.*; import java.io.*; import java.util.*; public class TimeServer {  public static void main(String[] args){   int port = 7000;   try{    ServerSocket ss = new ServerSocket(port);    while(true){     Socket client = ss.accept();     OutputStream os = client.getOutputStream();     ObjectOutputStream oos = new ObjectOutputStream(os);          oos.writeObject(new Date());     oos.flush();     oos.close();     client.close();    }   }catch(Exception e){    System.out.println(e.getMessage());   }  } }

TimeClient.java

import java.net.*; import java.io.*; import java.util.*; public class TimeClient {  public static void main(String[] args){   String server_ip;   Date date = null;   int port = 7000;   try{    BufferedReader read = new BufferedReader(new InputStreamReader(System.in));    System.out.println(" 타임 서버 시간 받아오기 ...");    System.out.print(" 타임 서버 아이피 입력 : ");    server_ip = read.readLine();        Socket client = new Socket(server_ip, port);    InputStream is = client.getInputStream();    ObjectInputStream ois = new ObjectInputStream(is);    date = (Date)ois.readObject();    System.out.println("현재 시간 : " + date);    ois.close();    client.close();   }catch(Exception e){    System.out.println(e.getMessage());   }  } }

서버를 돌린후 클라이언트를 돌리면 되것죵.
