} } In this assignment I need help to

Override and implement the equals(..) method for the Dog class. We'll consider one dog to be equivalent to another dog if their names, age, and likesFetch fields match exactly.Override and implement hashCode() for the Dog class. The method should calculate and return the hash value computed from the name, age, and likesFetch fields. Create a Tester class containing a main(..) method and instantiate three Dog objects named d1, d2, and d3. Instantiate the objects such that d1.equals(d2) but neither d1 nor d2 equal d3 in the lab above
