Implement a public class called Pet. Every pet has a String name and a double age, which are passed in that order to the Pet constructor. You should override equals to return true if two Pet instances have the same age and name. As a reminder, the signature of equals is public Boolean equals (Object other). If the argument to equals is null or not a Pet or a descendant of Pet you should return false.
Note that you can use the Java instance of operator to test whether an object is an instance of descendant of a particular class. In java, please.
