Consider the following interface:

interface Validate

{

boolean check(Object o);

}

Classes that implement Validate interface, check against specific conditions to evaluate the object O. For example, a class validateAge checks if a birth year indicated by the persons age is over 18 years old or not. If v is a validateAge object, then v.check(2001) returns true, and v.check(2003) returns false.

Write the class validateAge, and recall casting from a type to another.
