Write an equalsmethod for the Fish class; have it override the Object equals method. Two Fish are equal if they havethe same values of the instance variables vertabrates (a Boolean) and edible (a String).Design a class named Goldfish that extends Fish and implements Swimmer. Implement howToSwimto display the message It is swimming. Then design a class named Comet that extends Fish andimplements Swimmer. Implement howToSwim to display the message “It is swimming”.Draw a UML diagram that involves Swimmer, Goldfish, Comet and Fish. Write a testprogram that creates an array of five Fish objects. For each object in the array, display the result ofequals method with another object of the same array and invoke its howToSwim method if it isswimmer.
