DNA objects contain two strings, a rsid and a genotype. Create the instance variables with the appropriate privacy settings. Then create the structure of the constructor to take two parameters to match the instance variables. Make sure you set the privacy settings on the constructor correctly. (You do not need to complete the constructor). Note: Because there is no main method, your code will not execute (that's ok). Use the autograde to verify that you have the correct code. 1 public class DNA

Write a method named addall that could be placed inside the hashintset class. this method accepts another hashintset as a parameter and adds all elements from that set into the current set, if they are not already present. for example, if a set s1 contains [1, 2, 3] and another set s2 contains [1, 7, 3, 9], the call of s1.addall(s2); would change s1 to store [1, 2, 3, 7, 9] in some order. you are allowed to call methods on your set and/or the other set. do not modify the set passed in. this method should run in o(n) time where n is the number of elements in the parameter set passed in.
