使用Java Runtime从任何位置执行cl命令

try {
    // 执行cl命令
    Process process = Runtime.getRuntime().exec("cl");
    
    // 获取命令输出结果
    BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
    String line;
    while ((line = reader.readLine()) != null) {
        System.out.println(line);
    }
    
    // 等待命令执行完成
    int exitCode = process.waitFor();
    System.out.println("命令执行完成，退出码：" + exitCode);
} catch (IOException e) {
    e.printStackTrace();
} catch (InterruptedException e) {
    e.printStackTrace();
}

try {
    // 执行带参数的cl命令
    Process process = Runtime.getRuntime().exec(new String[]{"cl", "/?"});
    
    // 获取命令输出结果
    BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
    String line;
    while ((line = reader.readLine()) != null) {
        System.out.println(line);
    }
    
    // 等待命令执行完成
    int exitCode = process.waitFor();
    System.out.println("命令执行完成，退出码：" + exitCode);
} catch (IOException e) {
    e.printStackTrace();
} catch (InterruptedException e) {
    e.printStackTrace();
}
