Possible Duplicate Is it bad to explicitly compare against boolean constants e g if b false in Java In this NotePadProvider sample code I noticed that the author chose the form if values containsKey NoteColumns CREATED DATE false values put NoteColumns CREATED DATE now Over if values containsKey NoteColumns CREATED DATE values put NoteColumns CREATED DATE now Is there any advantage in the first form over the more logical one

if (boolean == false) vs. if (!boolean)

Apart from "readability", no. They're functionally equivalent.

_{("Readability" is in quotes because I hate == false and find ! much more readable. But others don't.)}
