airline name, flight number, and the flight's origin and destination
cities. Define the Flight constructor to accept and initialize all
instance data. Include getter and setter methods for all instance data.
Include a toString method that returns a one-line description of
the flight. Create a driver class called FlightTest , whose main
method instantiates and updates several Flight objects.
PP 4.7 Design and implement a class called Bulb that represents a light
bulb that can be turned on and off. Create a driver class called
Lights whose main method instantiates and turns on some Bulb
objects.
PP 4.8 Using the Die class defined in this chapter, design and implement
a class called PairOfDice , composed of two Die objects. Include
methods to set and get the individual die values, a method to roll
the dice, and a method that returns the current sum of the two
die values. Create a driver class called RollingDice2 to instanti-
ate and use a PairOfDice object.
PP 4.9 Design and implement a class called Building that represents
a graphical depiction of a building. Allow the parameters to
the constructor to specify the building's width and height. Each
building should be colored black and should contain a few ran-
dom windows of yellow. Create a program that draws a random
skyline of buildings.
PP 4.10 Write a program that displays a graphical seating chart for a
dinner party. Create a class called Diner (as in one who dines)
that stores the person's name, gender, and location at the dinner
table. A diner is graphically represented as a circle, color-coded
by gender, with the person's name printed in the circle.
PP 4.11 Create a class called Crayon that represents one crayon of a
particular color and length (height). Design and implement a
program that draws a box of crayons.
PP 4.12 Create a class called Star that represents a five-pointed star. Let
the constructor accept the width of the star and the coordinates
of the star's top point. Write a program that draws a sky con-
taining stars of various sizes.
PP 4.13 Modify the Fahrenheit program from this chapter so that it
displays a button that, when pressed, also causes the conversion
calculation to take place. That is, the user will now have the
option of either pressing Enter in the text field or pressing the
button. Have the listener that is already defined for the text field
also listen for the button push.
