java Socket 通讯的代码例子
实现Client端功能的ClientApp.Java原文件：import java.net.*;import java.io.*;import java.lang.*;public class ClientApp{public static void main(String args[]){ try { //创建通讯并且和主机Rock连接 Socket cSocket=new Socket("192.168.100.188",8018); //打开这个Socket的输入/输出流 OutputStream os=cSocket.getOutputStream(); DataInputStream is=new DataInputStream(cSocket.getInputStream()); int c; boolean flag=true; String responseline; while(flag) { //从标准输入输出接受字符并且写如系统 while((c=System.in.read())!=-1) { os.write((byte)c); if(c=='\n') { os.flush(); //将程序阻塞，直到回答信息被收到后将他们在标准输出上显示出来 responseline=is.readLine(); System.out.println("Message is:"+responseline); } } } os.close(); is.close(); cSocket.close(); } catch(Exception e) { System.out.println("Exception :"+ e.getMessage()); }}}
实现Server端功能的ServerApp.java原文件：
import java.net.*;import java.io.*;public class ServerApp{public static void main(String args[]){ try { boolean flag=true; Socket clientSocket=null; String inputLine; int c; ServerSocket sSocket=new ServerSocket(8018); System.out.println("Server listen on:"+sSocket.getLocalPort()); while(flag) { clientSocket=sSocket.accept(); DataInputStream is= new DataInputStream(new BufferedInputStream(clientSocket.getInputStream())); OutputStream os=clientSocket.getOutputStream(); while((inputLine=is.readLine())!=null) { //当客户端输入stop的时候服务器程序运行终止！ if(inputLine.equals("stop")) { flag=false; break; } else { System.out.println(inputLine); while((c=System.in.read())!=-1) { os.write((byte)c); if(c=='\n') { os.flush(); //将信息发送到客户端 break; } } } } is.close(); os.close(); clientSocket.close(); } sSocket.close(); } catch(Exception e) { System.out.println("Exception :"+ e.getMessage()); }}}
