用Java语言写一个鸿蒙系统的程序

import com.huawei.hiar.AREnginesSelector; import com.huawei.hiar.ARSession; import com.huawei.hiar.exceptions.*; public class HongMengSystem { private AREnginesSelector arEnginesSelector;// 鸿蒙系统的引擎选择器 public void init() { // 初始化鸿蒙系统的引擎选择器，并传入上下文参数，用于实例化AREngine。 arEnginesSelector = AREnginesSelector.createInstance(context); // 确定用户想要使用的AR引擎，可以是HUAWEI AR Engine或者ARKit/ARCore。 arEnginesSelector.setTargetEngine(ARSessionType); // 初始化鸿蒙系统，准备运行。如果初始化失败则会抛出异常。 try { arEnginesSelector.init(); LogUtil("Huawei AR Engine initialized"); } catch (UnavailableServiceNotInstalledException e) { LogUtil("Please install HUAWEI AR Service"); } catch (UnavailableClientSdkTooOldException e) { LogUtil("Please update HUAWEI AR Service"); } catch (UnavailableArcoreNotInstalledException e) { LogUtil("Please install Google Play Services for AR"); } catch (UnavailableDeviceNotCompatibleException e) { LogUtil("This device does not support Huawei AR Engine."); } catch (Exception e){ LogUtil(e); return false; } return true;} public void start() throws Exception{ // 启动鸿蒙AREngine服务 if (!arEnginesSelector .resume()) throw new Exception("Failed to start Huawei AREngine service");} public void stop(){ // 暂停鸿蒙AREngine服务 if (!arEnginesSelector .pause()) throw new Exception("Failed to stop Huawei AREngine service");} public void destroy(){ // 销毁鸿蒙AREngine服务 if (!arEngines
