运行程序：
客户端接收服务端返回的消息
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;//建立TCP客户端
public class ServerSocketDemo3
{public static void main(String[] args ) throws Exception{System.out.println("TCP协议服务端和客户端交互\n客户端启动");//建立TCP客户端Socket socket = new Socket("192.168.3.4",10002);OutputStream out = socket.getOutputStream();out.write("我来了".getBytes());//读取服务端返回的数据InputStream in = socket.getInputStream();byte[] buf = new byte[1024];int len = in.read(buf);String text = new String(buf,0,len);System.out.println("客户端："+text);socket.close();}
}
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;public class ServerSocketDemo4 {public static void main(String[] args) throws Exception {// 建立TCP服务端System.out.println("服务端启动");ServerSocket ss = new ServerSocket(10002);Socket s = ss.accept();String ip = s.getInetAddress().getHostAddress();InputStream in = s.getInputStream();byte[] buf = new byte[1024];int len = in.read(buf);String text = new String(buf,0,len);System.out.println(ip+" "+text);OutputStream out = s.getOutputStream();out.write("数据传输成功".getBytes());s.close();ss.close();}}
客户端输入小写字母，发送到服务端
用血端将小写字母转换成大写字母返回客户端
双窗口
