[Java网络编程基础]TCP发送和接收数据

代码如下:

package ClientPack;import java.io.IOException;import java.io.OutputStream;import .InetAddress;import .Socket;import .UnknownHostException;public class ClientDemo {public static void main(String[] args) throws IOException {// Socket s = new Socket(InetAddress.getByName("192.168.1.123"),10000);Socket s = new Socket("192.168.1.123",12345);OutputStream os = s.getOutputStream();os.write("hello,tcp,我来了".getBytes());s.close();}}

代码如下:

package ClientPack;import java.io.IOException;import java.io.InputStream;import .ServerSocket;import .Socket;public class ServerDemo {public static void main(String[] args) throws IOException {ServerSocket ss = new ServerSocket(12345);Socket s = ss.accept();InputStream is = s.getInputStream();byte[] bys = new byte[1024];int len = is.read(bys);String data = new String(bys,0,len);System.out.println("数据是"+data);s.close();ss.close();}}
