Chapter 8, Problem 5E

Create a class Square derived from DrawableShape, as described in the previous exercise. A Square object should know the length of its sides The class should have an accessor method and a mutator method for this length. It should also have methods for computing the area and perimeter of the square. Although characters are taller than they are wide—so the number of characters in the vertical sides will differ from the number in the horizontal sides—you need not worry about this detail when drawing the square.

Write a FancyCar class to support basic operations such as drive, add gas, honk horn, and start engine. FancyCar.java is provided with method stubs. Follow each step to gradually complete all methods. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main() method includes basic method calls. Add statements in main() as methods are completed to support development mode testing. Step 0. Declare private fields for miles driven as shown on the odometer (int), gallons of gas in tank (double), miles per gallon or MPG (double), driving capacity (double), and car model (String). Note the provided final variable indicates the gas tank capacity of 14.0 gallons. Step 1 (2 pts). 1) Complete the default constructor by initializing the odometer to five miles, tank is full of gas, miles per gallon is 24.0, and the model is "Old Clunker". 2)…
