网络连接练习

服务器端

public class TcpServer {
    public static void main(String[] args) throws IOException {
        ServerSocket serverSocket=new ServerSocket(999);

        System.out.println("开始监听");
       Socket socket=serverSocket.accept(); // 铸锻
        InputStream inputStream=socket.getInputStream();
        byte[] buffer=new byte[100];
        System.out.println("开始读数据");
        int len =inputStream.read(buffer);

        String string = new String(buffer,0,len);
        System.out.println(string);
        System.out.println("退出");

客户端

public class TcpClient {
    public static void main(String[] args) throws IOException {

        Socket socket=new Socket("10.25.41.36",999);
        String str = "nihao 龙哥";

        byte[] buffer = str.getBytes();



        OutputStream os = socket.getOutputStream();
        os.write(buffer,0,buffer.length);

        System.out.println("退出");
    }


    }
