使用TCP协议编写一个网络程序,设置服务器端的监听端口是8002,当与客户端建立连接后,服务器端向客户端发送数据“Hello, world”,客户端收到数据后打印输出。
package Tcp;
import java.io.OutputStream;
import java.net.*;
public class ServerTest2 {
public static void main(String[] args) throws Exception { new TCPserver().listen();}
}
class TCPserver{
public void listen()throws Exception{
ServerSocket serverSocket = new ServerSocket(8002);
Socket client = serverSocket.accept();
OutputStream os = client.getOutputStream();
os.write((“Hello Worls”).getBytes());
Thread.sleep(5000);
System.out.println(“交互结束”);
os.close();
client.close();
}
}
package Tcp;
import java.io.InputStream;
import java.net.*;
public class ClientTest {
public static void main(String[] args) throws Exception { new TCPclient().connect();}
}
class TCPclient{
private static final int PORT = 8002;
public void connect()throws Exception{
Socket client = new Socket(InetAddress.getLocalHost(),PORT);
InputStream is = client.getInputStream(); byte[] buf = new byte[1024]; int len = is.read(buf); System.out.println(new String(buf,0,len)); client.close();}
}
