socket程序例子
服务端：
ServerSocket server1 = new ServerSocket(8080); System.out.println("Started: "+server1);//服务器信息 /*阻塞在这里，等客户端连接,该例子只能有一个客户连接到一个端口，如果要能多个连接的，要为每个连接的开个线程，建立连接后，就和一个客户端建立了socket连接，然后就用socket1.getInputStream()和socket1.getOutputStream()来收发信息了;*/

Socket socket1 = server1.accept(); System.out.println("socket1: "+socket1);//获得客户端信息 InputStream ins = socket1.getInputStream(); //读客户发来的信息 BufferedReader in = new BufferedReader(new InputStreamReader(ins));//客户端输入信息 OutputStream outs = socket1.getOutputStream(); //准备向客户发送信息
PrintStream out = new PrintStream(outs);//键盘输入，后输出客户端

BufferedReader userin = new BufferedReader(new InputStreamReader(System.in)); while(true) { System.out.println("wait client1....");
str = in.readLine();
//客户端 System.out.println("client1:"+str);
if(str.equals("end"))break; str = str=userin.readLine();
//键盘输入 out.println(str); if(str.equals("end"))break; } socket1.close(); server1.close();

 

客户端：
InetAddress addr=InetAddress.getByName("127.0.0.1"); Socket socket1 = new Socket(addr,8080);
System.out.println("socket1:"+socket1); InputStream ins = socket1.getInputStream(); BufferedReader in = new BufferedReader(new InputStreamReader(ins));
//客户端输入信息
OutputStream outs = socket1.getOutputStream(); PrintStream out = new PrintStream(outs);
//从键盘输入，然后后输出到服务端端
BufferedReader userin = new BufferedReader(new InputStreamReader(System.in));
while(true)
{ System.out.println("please input char...");
str1 = userin.readLine(); out.println(str1);
System.out.println("waiting for server...");
if(str1.equals("end")) { break; } str1 = in.readLine();
System.out.println("svrver:t"+str1);
if(str1.equals("end")) { break; } } socket1.close();
