Java 使用 Socket 实现客户端和服务器的信息交互

服务器

public class Server{
	
	private ServerSocket serverSocket;
	private Socket socket;
	private BufferedReader in;
	private PrintWriter out;
	
	public Server() {
		try {
			//	定义连接端口
			serverSocket = new ServerSocket(10000);
			while(true) {
				//	等待客户端连接
				socket = serverSocket.accept();
				//	获取本机地址
				String RemoteIP = socket.getInetAddress().getHostAddress();
				//	获取本机端口号
				String RemotePort = ":" + socket.getLocalPort();
				System.out.println("服务器：有一个用户进来了! IP 地址为：" + RemoteIP + RemotePort);
				in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
				//	获取用户输入的内容
				String line = in.readLine();
				System.out.println("用户：" + line);
				out = new PrintWriter(socket.getOutputStream(),true);
				out.println("服务器：已经收到消息");
				//	关闭资源
				out.close();
				in.close();
				socket.close();
			}
		}catch(IOException e)
