(9.1.2, 9.1.3, 9.1,4, 9.1.5)

Draw the complete diagram for Coffee with all the method signatures included in the method compartment. Solution

Remember the class Image from exercise 2 for creating Web pages. Develop the following methods for this class:

isPortrait, which determines whether the image is taller than wider;
size, which computes how many pixels the image contains;
isLarger, which determines whether one image contains more picture than some other image. Solution

Develop the following methods for the class House from exercise 2:

isBigger, which determines whether one house has more rooms than some other house;
thisCity, which checks whether the advertised house is in some given city (assume we give the method a city name);
sameCity, which determines whether one house is in the same city as some other house.

Don't forget to test these methods. Solution

Here is a revision of the problem of managing a runner's log (see figure fig:entry):

Develop a program that manages a runner's training log. Every day the runner enters one entry concerning the day's run. ...For each entry, the program should compute how fast the runner ran. ...

Develop a method that computes the pace for a daily entry. Solution
