JSpecify provides a standardized set of annotations for null safety in Java, helping developers explicitly declare nullness expectations and catch NullPointerException issues at compile time. The tool offers annotations like @Nullable, @NonNull, and @NullMarked for gradual adoption across codebases, with growing support from IDEs and static analysis tools like Checker Framework and NullAway.
