Question

Assume that I have an annotation that generates a warning. The annotation is on a method.

e.g.

@AnnotationThatGeneratesAWarning
public void doSomething() {
  //stuff
}

Can I use @SuppressWarnings to suppress it? Does @SuppressWarnings work with warnings generated by annotations, or just on warnings generated by the method itself?

Answer 1

What IDE are you using? What’s the code that generates the warning?. A good IDE will generally suggest the String to use in the @SuppressWarnings, but it’s better to first try to fix the warning, if that’s not possible and as a last resource use @SuppressWarnings.

EDIT :

You can tell that @SuppressWarnings won’t work with other annotations looking at its documentation. As you can see:

@Target(value={TYPE,FIELD,METHOD,PARAMETER,CONSTRUCTOR,LOCAL_VARIABLE})

The targets do not include ANNOTATION_TYPE, meaning that @SuppressWarnings can not be applied to other annotations.
