PLEASE ANSWER TO ALL MY QUESTIONS. 1. What does it mean to "parameterize a data type"? 2. In our ArrayList class, we still used an array as the underlying data structure. What data type did we declare it to be and why was that necessary? 3. In SuperAndSub, what do the default constructors for each of the classes do?

4. In SuperAndSub, when the SubClass object is created which class constructor completes execution first? Why do you think that is the case? 5. What was the hardest part of this lab for you and why was it hard.
