Agenda

• Announcements
  • Lab 0: Setting Up and Refresher due at the start of your lab this week
  • Problem Set 1 due Wednesday night, keep those submissions coming
• More Java You Know
• In-class exercises (5 assignment points)
  • Simplify the following using a ternary operator, eliminating the need for the if statement:

            if (numPeople == 1) {
                System.out.println("1 person attended the meeting.");
            }
            else {
                System.out.println(numPeople + " people attended the meeting.");
            }
    

  • Draw four memory diagrams, one where XXXXXX is each of (i) an ArrayList, (ii) a singly-linked list with only a head reference, (iii) a singly-linked circular list with only a tail reference, and (iv) a doubly-linked list with both head and tail references. The add method does not take a position at which to add, and will choose the most efficient position for the given structure. In cases where it is similarly efficient to add at the beginning or at the end, it will add at the beginning.

       List<Integer> x = new XXXXXX<Integer>();
       x.add(1);
       x.add(2);
       x.add(3);
