关于socket的简单的客户服务端编程

public class Server {
private ServerSocket ss;
private Socket socket;// 用来接收客户端的socket
private BufferedReader in;// 读取客户端发来的信息


public Server() {
try {
ss = new ServerSocket(10000);
while (true) {
System.out.println("等待接收：");
socket = ss.accept();// 连接客户端
System.out.println("从" + socket.getRemoteSocketAddress()
+ "连接成功");


in = new BufferedReader(new InputStreamReader(
socket.getInputStream()));// 得到客户端的输入流
String socketText = in.readLine();// 获取客户端的内容
System.out.println(" 客户端说:" + socketText);
in.close();
socket.close();
}


} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}


}


/**
* @param args
*/
public static void main(String[] args) {
new Server();
}

}

运行结果

先运行服务器显示

等待接收：

然后运行客户端：请输入信息：我爱java

服务器显示：从/127.0.0.1:60139连接成功
 客户端说:我爱java
