java lang UnsupportedOperationException     Thrown to indicate that the requested operation is not supported

User · Answer

Differentiate between the two cases you named    To indicate that the requested operation is not supported and most likely never will  throw an UnsupportedOperationException  To indicate the requested operation has not been implemented yet  choose between this    Use the NotImplementedException from apache commons-lang which was available in commons-lang2 and has been re-added to commons-lang3 in version 3 2  Implement your own NotImplementedException  Throw an UnsupportedOperationException with a message like  Not implemented  yet

If you create a new  not yet implemented  function in NetBeans  then it generates a method body with the following statement   throw new java lang UnsupportedOperationException  Not supported yet       Therefore  I recommend to use the UnsupportedOperationException
