I like using question mark at the end of method/function names in other languages. Java doesn't let me do this. As a workaround how else can I name boolean returning methods in Java? Using an is, has, should, can in the front of a method sound okay for some cases. Is there a better way to name such methods?
For e.g. createFreshSnapshot?
I want to post this link as it may help further for peeps checking this answer and looking for more java style convention
Java Programming Style Guidelines
Item "2.13 is prefix should be used for boolean variables and methods." is specifically relevant and suggests the is prefix.
The style guide goes on to suggest:
There are a few alternatives to the is prefix that fits better in some situations. These are has, can and should prefixes:
boolean hasLicense();
boolean canEvaluate();
boolean shouldAbort = false;
If you follow the Guidelines I believe the appropriate method would be named:
shouldCreateFreshSnapshot()
I want to point a different view on this general naming convention, e.g.:
see java.util.Set: boolean add(E e)
where the rationale is:
do some processing then report whether it succeeded or not.
While the return is indeed a boolean the method's name should point the processing to complete instead of the result type (boolean for this example).
Your createFreshSnapshot example seems for me more related to this point of view because seems to mean this: create a fresh-snapshot then report whether the create-operation succeeded. Considering this reasoning the name createFreshSnapshot seems to be the best one for your situation.
