The level of difficulty of these problems varies wildly. Some are entirely appropriate for a high school course. Others definitely inappropriate. Although problems are categorized by topics, this should not be taken very seriously. Many problems fit equally well in several different topics.

Please answer all of the questions perfectly (no short answer please). I will thumbs up/rate if it's correct. Please it's urgent.

In java,

Design an interface named Swimmer with a void method named howToSwim (). Every class of a swimmer object must implement the Swimmer interface. Design a class named Fish. Write an equals method for the Fish class; have it override the Object equals method. Two Fish are equal if they have the 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 howToSwim to display the message It is swimming. Then design a class named BubbleEye that extends Fish and implements Swimmer. Implement howToSwim to display the message "It is swimming". Draw a UML diagram that involves Swimmer, Goldfish, BubbleEye and Fish. Write a test program that creates an array of five Fish objects. For each object in the array, display the result of equals method with another object of the same array and invoke its howToSwim method if it is swimmer
