利用Socket连接到某个端口并打印出它所找到的信息

package socket;

import java.io.IOException;

import java.io.InputStream;

import java.net.Socket;

import java.net.UnknownHostException;

import java.util.Scanner;

public class SocketTest {

public static void main(String[] args) throws IOException {

// TODO Auto-generated method stub

try(Socket s = new Socket("time-A.timefreq.bldrdoc.gov", 13)){

InputStream inStream = s.getInputStream();

Scanner in = new Scanner(inStream);

while(in.hasNextLine()){

String line =in.nextLine();

System.out.println(line);

}

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}
