If want to access the public methods of a class
you should use getMethod() instead of getDeclaredMethod().
getMethod() returns the public method in the
class or in one of its supperclasses
getDeclaredMethod() returns only the method from the class where it
is defined it also returns private,protected or default scope methods.
