public final class Method extends AccessibleObject implements GenericDeclaration, Member
Method provides information about, and access to, a single method
on a class or interface. The reflected method may be a class method
or an instance method (including an abstract method).
A Method permits widening conversions to occur when matching the
actual parameters to invoke with the underlying method's formal
parameters, but it throws an IllegalArgumentException if a
narrowing conversion would occur.
