Chapter 4: Making the Most of Variables and Their Values 81 Listing 4-3: Using the int Type import static java.lang.System.out; class ElevatorFitter { public static void main(String args[]) { int weightOfAPerson; int elevatorWeightLimit; int numberOfPeople; weightOfAPerson = 150; elevatorWeightLimit = 1400; numberOfPeople = elevatorWeightLimit / weightOfAPerson; out.print( You can fit ); out.print(numberOfPeople); out.println( people on the elevator. ); } } The story behind the program in Listing 4-3 takes some heavy-duty explaining. So here goes: You have a hotel elevator whose weight capacity is 1,400 pounds. One weekend, the hotel hosts the Brickenchicker family reunion. A certain branch of the Brickenchicker family has been blessed with identical dectuplets (ten siblings, all with the same physical characteristics). Normally, each of the Brickenchicker dectuplets weighs exactly 145 pounds. But on Saturday, the family has a big catered lunch, and, because lunch included strawberry shortcake, each of the Brickenchicker dectuplets now weighs 150 pounds. Immediately after lunch, all ten of the Brickenchicker dectuplets arrive at the elevator at exactly the same time. (Why not? All ten of them think alike.) So, the question is, how many of the dectuplets can fit on the elevator? Now remember, if you put one ounce more than 1,400 pounds of weight on the elevator, the elevator cable breaks, plunging all dectuplets on the elevator to their sudden (and costly) deaths. The answer to the Brickenchicker riddle (the output of the program of Listing 4-3) is shown in Figure 4-4. Figure 4-4: Save the Brickenchickers.
