socket server-client端通信的例子

server端例子

public class socketServer {
	public static void main(String[] args) throws IOException {
		ServerSocket server = new ServerSocket(5678);
		Socket client = server.accept();
		BufferedReader in = new BufferedReader(new InputStreamReader(client
				.getInputStream()));
		PrintWriter out = new PrintWriter(client.getOutputStream());
		while (true) {
			String str = in.readLine();
			System.out.println(str);
			out.println("server display :has receiv...");
			out.flush();
			if (str.equals("end"))
				break;
		}
		client.close();
	}
}

 
 

 

客户端实例

public class socketClient {
	static Socket server;
	public static void main(String[] args) throws Exception {
		server = new Socket(InetAddress.getLocalHost(), 5678);
		BufferedReader in = new BufferedReader(new InputStreamReader(server
				.getInputStream()));
		PrintWriter out = new PrintWriter(server.getOutputStream());
		BufferedReader wt = new BufferedReader(new InputStreamReader(System.in));

		while (true) {
			String str = wt.readLine();
			out.println("client display:"+str);
			out.flush();
			if (str.equals("end")) {
				break;
			}
			System.out.println(in.readLine());
		}
		server.close();
	}
