(20 pts) Assume two cows are the same if they have the same name. Write class Cow and the necessary methods to make main this work, and put a print statement inside each method. Then on the lines next to each call to add, write what the methods would print. class HashSetPractice * On the comment lines provided, write *a11* that is printed as a * result of each line of code. public static void main (String[] args) HashSet herd - new HashSet); herd.add (new Cow ("A")); System.out.println (); herd.add (new Cow ("Alba") ) System.out.println (); herd.add (new Cow ("A")); System.out.println ) herd.add (new Cow ("Aga")) System.out.println (); herd.add (new Cow ("A")); System.out.println ); System.out.println (herd.size ()); //
