I'd prefer Class.getMethods.  getDeclaredMethods won't look at inherited 
methods, which is not normally what you want.

And you can skip isAnnotationPresent and just go for getAnnotations.  It 
returns a 0 length array if no annotations are present. Your loop 
iterator should catch that by default, no need for additional checks or 
logic in the driving code.
