在Java中启动连接的telnet cmd窗口

import java.io.IOException;

public class TelnetExample {
    public static void main(String[] args) {
        try {
            // 创建ProcessBuilder对象，并设置要执行的命令
            ProcessBuilder processBuilder = new ProcessBuilder("cmd.exe", "/c", "telnet");

            // 启动进程
            Process process = processBuilder.start();

            // 等待进程执行完成
            int exitCode = process.waitFor();

            // 检查进程的退出码
            if (exitCode == 0) {
                System.out.println("telnet连接成功");
            } else {
                System.out.println("telnet连接失败");
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
