CSIS 505 CSIS 505 Homework 1 Instructions CSIS 505 Exception Handling Assignment Instructions Overview In this assignment, you will complete two exercises that will allow you to practice your skill with the topics of interfaces and exceptions that you learned about in the Learn section. Instructions 1. Refer to the Assignments Grading Rubric before you begin this assignment. 2. Complete the detailed instructions for each exercise included in the sections below. For each exercise, begin with a new Java project. 3. As you write your code, provide all pertinent documentation in the form of JavaDoc comments for all classes and methods. a. All class-level comments must include a description of the class along with your name and links to any outside resources you used (other than the textbook) while writing your code. b. Each method must also have a comment that indicates the purpose of the method and, if applicable, the purpose of all parameters and return value. c. Additional in-line comments must be used to explain complex algorithms or unique solutions to the problem. 4. After you have completed the exercises for this assignment, submit a Word document containing screenshots of the assignment executing on your machine. Exercise 1 Governments and companies worldwide are becoming increasingly concerned with carbon footprints (annual releases of carbon dioxide into the atmosphere) from buildings burning various types of fuel for heat, vehicles burning fuels for power, and the like. 1. Create 3 small classes unrelated by inheritance: Building, Car, and Bicycle 2. Give each class the unique attributes and behaviors as specified in the class diagram in Figure 1 below. Create a single constructor for each class to allow consumers of the class to provide initial values for each attribute. 3. Write an interface CarbonFootprint with a getCarbonFootprint method. 4. Have each of your classes implement that interface so that its getCarbonFootprint method calculates the appropriate carbon footprint for that class, as specified below: a. Building footprint = ([monthly gas bill / 10.68] * 119.58 * 12) + ([monthly electric bill / 0.1188] * 1232 * 12) b. Car footprint = miles driven per year / miles per gallon * 19.82 c. Bicycle footprint = miles traveled per month * 0.9 5. Write an application that does the following: a. Creates objects of each of the 3 classes b. Places references to those objects in an array of CarbonFootprint c. Iterates through the array, polymorphically invoking each object’s getCarbonFootprint method d. For each object, print identifying information, such as miles traveled or monthly bill amount, along with the object’s carbon footprint. Exercise 2 Extend Exercise 1 by creating and demonstrating the use of an InvalidFootprintException class. 1. Create the 4 constructors as discussed in this module/week’s presentations. 2. Extend the appropriate superclass. 3. Throw the InvalidFootprintException in the constructor of the Building, Car, and Bicycle classes if any of the provided parameter values are negative. 4. Add code in your main method that handles the InvalidFootprintException, and write code that demonstrates that your handler works (i.e., write code that purposefully causes the InvalidFootprintException to be thrown, but then ensure that it does not crash your program). Instead of crashing, your main method must print a message to the error stream that an invalid footprint was detected. Figure 1. Exercise 1 Class Diagram Page 1 of 3 Page 4 of 4 Page 1 of 2
