    <p>My java compiler is complaining that my code uses "unchecked or unsafe operations". Any idea which lines are causing that in the two code snippets?</p> <pre><code> @SuppressWarnings("unchecked") private final void prepareChannelAccountStringsParserImplementedClassConstructor() { try { String channelAccountStringsParserImplementedClassName = channelIdentifier + "AccountStringsParser"; Class channelAccountStringsParserImplementedClass = Class.forName(channelAccountStringsParserImplementedClassName); Class[] channelAccountStringsParserImplementedClassArguments = new Class[1]; channelAccountStringsParserImplementedClassArguments[0] = String.class; channelAccountStringsParserImplementedClassConstructor = channelAccountStringsParserImplementedClass.getConstructor(channelAccountStringsParserImplementedClassArguments); channelAccountStringsParserImplementedParseMethod = channelAccountStringsParserImplementedClass.getMethod("parse", String.class); channelAccountStringsParserGetRequestIDMethod = channelAccountStringsParserImplementedClass.getMethod("getRequestID"); } catch (ClassNotFoundException classNotFoundException) { NotifyMeListenersLogsDB notifyMeListenersLogsDB = DatabaseController.getInstance().getNotifyMeListenersLogsDB(); notifyMeListenersLogsDB.writeDeveloperException(classNotFoundException); } catch (NoSuchMethodException noSuchMethodException) { NotifyMeListenersLogsDB notifyMeListenersLogsDB = DatabaseController.getInstance().getNotifyMeListenersLogsDB(); notifyMeListenersLogsDB.writeDeveloperException(noSuchMethodException); } } @SuppressWarnings("unchecked") public synchronized final void requestChannelAccountsCompletionSuccess(String responseContent) { Object channelAccountStringsParserImplementedInstance; ArrayList&lt;ChannelAccount&gt; channelAccounts = null; String requestID = null; try { channelAccountStringsParserImplementedInstance = channelAccountStringsParserImplementedClassConstructor.newInstance(responseContent); channelAccounts = (ArrayList&lt;ChannelAccount&gt;) channelAccountStringsParserImplementedParseMethod.invoke(channelAccountStringsParserImplementedInstance, responseContent); requestID = (String) channelAccountStringsParserGetRequestIDMethod.invoke(channelAccountStringsParserImplementedInstance); } catch (InstantiationException instantiationException) { NotifyMeListenersLogsDB notifyMeListenersLogsDB = DatabaseController.getInstance().getNotifyMeListenersLogsDB(); notifyMeListenersLogsDB.writeDeveloperException(instantiationException); } catch (IllegalAccessException illegalAccessException) { NotifyMeListenersLogsDB notifyMeListenersLogsDB = DatabaseController.getInstance().getNotifyMeListenersLogsDB(); notifyMeListenersLogsDB.writeDeveloperException(illegalAccessException); } catch (InvocationTargetException invocationTargetException) { NotifyMeListenersLogsDB notifyMeListenersLogsDB = DatabaseController.getInstance().getNotifyMeListenersLogsDB(); notifyMeListenersLogsDB.writeDeveloperException(invocationTargetException); } channelAccountStringsParserImplementedInstance = null; try { startChannelConnections(channelAccounts); isStarted = true; LoadBalancer.getInstance().sendSuccessAcknowledgement(requestID); } catch (NotifyMeListenersApplicationInitializationException notifyMeListenersApplicationInitializationException) { NotifyMeListenersLogsDB notifyMeListenersLogsDB = DatabaseController.getInstance().getNotifyMeListenersLogsDB(); notifyMeListenersLogsDB.writeNotifyMeListenersException(notifyMeListenersApplicationInitializationException); System.exit(1); } } </code></pre> <p>Of course, I put the @SuppressWarnings to suppress it, but I'd like to know the cause. Anyone can help?</p>
