    <p>I have this warning on most of my classes and not sure why is that. This happens on both public normal classes and final classes which have private constructors, some no constructor at all. I tried changing my private class methods to protected, doesn't help.<br> Any suggestions on how to turn this off?</p> <p>Here's a class example</p> <pre><code>public final class PlanBenefitManagerAssembler { private static final Logger LOGGER = Logger.getLogger(PlanBenefitManagerAssembler.class); /** * No Instance of the this class is allowed. */ private PlanBenefitManagerAssembler() { } public static List&lt;BenefitDecisionDetailsBean&gt; assembleBenefitDecisionDetailsBean( List&lt;BenefitDetails&gt; benefitDecisionDetailsList, int relationalSequenceNumber) { LOGGER.debug("Enter assembleBenefitDecisionDetailsBean"); List&lt;BenefitDecisionDetailsBean&gt; benefitDecisionDetailsBeanList = new ArrayList&lt;BenefitDecisionDetailsBean&gt;(); for (BenefitDetails benefitDecisionDetails : benefitDecisionDetailsList) { BenefitDecisionDetailsBean benefitDecisionDetailsBean = new BenefitDecisionDetailsBean(); benefitDecisionDetailsBean.setBenefitTypeCode(benefitDecisionDetails.getBenefitTypeCode()); benefitDecisionDetailsBean.setRelationSequenceNumber(relationalSequenceNumber); benefitDecisionDetailsBean.setBenefitStatusDescription( benefitDecisionDetails.getBenefitStatusDescription()); benefitDecisionDetailsBean.setBenefitStatusCode(benefitDecisionDetails.getBenefitStatusCode()); benefitDecisionDetailsBean.setBenefitUnderwritingStatusCode( benefitDecisionDetails.getBenefitUnderwritingStatusCode()); benefitDecisionDetailsBean.setBenefitUnderwritingStatusDescription( benefitDecisionDetails.getBenefitUnderwritingStatusDescription()); benefitDecisionDetailsBean.setBenefitChangeReasonCode( String.valueOf(benefitDecisionDetails.getBenefitChangeReasonCode())); benefitDecisionDetailsBean.setBenefitChangeReasonDescription( benefitDecisionDetails.getBenefitChangeReasonDescription()); benefitDecisionDetailsBean.setComponentNumber(benefitDecisionDetails.getBenefitNumber()); benefitDecisionDetailsBean.setBenefitVisible(benefitDecisionDetails.isExplicitBenefitDecisionRequired()); benefitDecisionDetailsBean.setModelChanged(false); // * Set BenefitLoading and BenefitExclusion List&lt;ExclusionDetailsBean&gt; exclusionDetailsBeanList = PlanBenefitManagerAssembler.assembleExclusionDetailsList(benefitDecisionDetails .getBenefitExclusionsDetailsList().getBenefitExclusionsDetailsList()); List&lt;LoadingDetailsBean&gt; loadingDetailsBeanList = PlanBenefitManagerAssembler.assembleLoadingDetailsList(benefitDecisionDetails .getBenefitLoadingsDetailsList().getBenefitLoadingsDetailsList()); benefitDecisionDetailsBean.setExclusionDetailsBeanList(exclusionDetailsBeanList); benefitDecisionDetailsBean.setLoadingDetailsBeanList(loadingDetailsBeanList); benefitDecisionDetailsBeanList.add(benefitDecisionDetailsBean); } LOGGER.debug("Exit assembleBenefitDecisionDetailsBean"); return benefitDecisionDetailsBeanList; } } </code></pre>

    3. COnot sure but i would think that checstyle is looking to see if the class is instantiable with a public construcor and if not is saying to itself 'well it must be an abstract class yet it hasn't been declared abstract so lets warn the user'

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
