Eliminate every unchecked warnings that you can. If you can’t eliminate a warning, but you can prove that the code that provoked the warning is typesafe, then (and only then) suppress the warning with an @SuppressWarnings(“unchecked”) annotation.

The SuppressWarnings annotation can be used on any declaration, from an individual local variable declaration to an entire class. Always use the SuppressWarnings annotation on the smallest scope possible.

Every time you use a @SuppressWarnings(“unchecked”) annotation, add a comment saying why it is safe to do so.
