アナログプログラミングソケットまたはマイクロチャネルQQのインスタントメッセージング（2開いているTomcatのテストを実行することができます）

以下是socket编程代码
/** 客户端*/
import java.net.InetAddress;
import java.net.Socket;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.BufferedReader;
import java.io.IOException;

public class ChatClient {
public static void main(String[] args) throws IOException {
// 建⽴TCP客户端服务
//	Socket socket = new Socket(InetAddress.getLocalHost(), 9090);
byte[] addr = {-64,-88,-108,2};
InetAddress address = InetAddress.getByAddress(addr);
Socket socket = new Socket(address, 9090);
// 获取Socket输出流对象
OutputStreamWriter socketOut = new OutputStreamWriter(socket.getOutputStream());
// 获取Socket输⼊流对象
BufferedReader socketReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
// 获取键盘输⼊流对象，读取数据
BufferedReader keyboardReader = new BufferedReader(new InputStreamReader(System.in));
String line = null;
System.out.print(“我说：”);
while ((line = keyboardReader.readLine()) != null) {
socketOut.write(line + “\n”);
// 刷新
socketOut.flush();
// 读取服务器端返回的数据
line = socketReader.readLine();
System.out.println(“服务器：” + line);
System.out.print(“我说：”);
}
socket.close();
}
}
