Given the following class import java. util. arraylist; public class rectangletester { public static void main(string[ ] args) { arraylist shapes = new arraylist(); shapes. add(new rectangle(1, 1)); shapes. add(new rectangle(2, 2)); shapes. add(new rectangle(3, 3)); shapes. add(new rectangle(4, 4)); rectangle datarecord; for(int index = 0; index < shapes. size(); index++) { datarecord = shapes. get(index); datarecord. calcrectarea(); datarecord. calcrectperimeter(); } } } which of the following could not be a constructor for the rectangleclass? i. rectangle(int s1, int s2) { myside1 = s1; myside2 = s2; } ii. rectangle(s1, s2) { myside1 = s1; myside2 = s2; } iii. rectangle() { }
