JSL 1 7  The Oracle documentation mentions    unchecked  Unchecked warnings are identified by the string  unchecked    deprecation  A Java compiler must produce a deprecation warning when a type  method  field  or constructor whose declaration is annotated with the annotation  Deprecated is used  i e  overridden  invoked  or referenced by name   unless        The use is within an entity that is annotated to suppress the warning with the annotation  SuppressWarnings  deprecation    or   It then explains that implementations can add and document their own      Compiler vendors should document the warning names they support in conjunction with this annotation type  Vendors are encouraged to cooperate to ensure that the same names work across multiple compilers

All values are permitted  unrecognized ones are ignored    The list of recognized ones is compiler specific     In The Java Tutorials unchecked and deprecation are listed as the two warnings required by The Java Language Specification  therefore  they should be valid with all compilers      Every compiler warning belongs to a category  The Java Language Specification lists two categories  deprecation and unchecked    The specific sections inside The Java Language Specification where they are defined is not consistent across versions  In the Java SE 8 Specification unchecked and deprecation are listed as compiler warnings in sections 9 6 4 5   SuppressWarnings and 9 6 4 6  Deprecated  respectively   For Sun s compiler  running javac -X gives a list of all values recognized by that version   For 1 5 0 17  the list appears to be    all deprecation unchecked fallthrough path serial finally

And this seems to be a much more complete list  where I found some warnings specific to Android-Studio that I couldn t find elsewhere  e g  SynchronizeOnNonFinalField   https   jazzy id au 2008 10 30 list of suppresswarnings arguments html  Oh  now SO s guidelines contraddict SO s restrictions  On one hand  I am supposed to copy the list rather than providing only the link  But on the other hand  this would exceed the maximum allowed number of characters  So let s just hope the link won t break

A new favorite for me is  SuppressWarnings  WeakerAccess   in IntelliJ  which keeps it from complaining when it thinks you should have a weaker access modifier than you are using  We have to have public access for some methods to support testing  and the  VisibleForTesting annotation doesn t prevent the warnings   ETA   Anonymous  commented  on the page  MattCampbell linked to  the following incredibly useful note      You shouldn t need to use this list for the purpose you are   describing  IntelliJ will add those SuppressWarnings for you   automatically if you ask it to  It has been capable of doing this for   as many releases back as I remember       Just go to the location where you have the warning and type Alt-Enter    or select it in the Inspections list if you are seeing it there     When the menu comes up  showing the warning and offering to fix it for   you  e g  if the warning is  Method may be static  then  make static    is IntellJ s offer to fix it for you   instead of selecting  enter     just use the right arrow button to access the submenu  which will have   options like  Edit inspection profile setting  and so forth  At the   bottom of this list will be options like  Suppress all inspections for   class    Suppress for class    Suppress for method   and occasionally    Suppress for statement   You probably want whichever one of these   appears last on the list  Selecting one of these will add a    SuppressWarnings annotation  or comment in some cases  to your code   suppressing the warning in question  You won t need to guess at which   annotation to add  because IntelliJ will choose based on the warning   you selected

I noticed that   noinspection can be auto-generated in IntelliJ   make sure you have not already a plan  SuppressWarninigs before the statement Now you can auto-generate the specific   noinspection by hitting Alt Enter when you have the warning selected and then use the right arrow key to see the Suppress for     option   Ended up here when I wanted to suppress a  switch has too few case labels  warning from IntelliJ  I did not find a complete List for IntelliJ s  SuppressWarning support but   noinspection did the trick for me
