iLab 7 of 7: Putting It All Together
iLAB OVERVIEW
Scenario and Summary
This week, you will be implementing inheritance by creating a generic Racer superclass along with two subclasses
called StreetTuner and HotRod. You will make the Racer class abstract and include the abstract method IsDead in the
Racer class.

Capture the console output window and paste it into a Word document.
Zip the project folder.
Put the zip file and screenshots (Word document) in the Dropbox.
iLAB STEPS
STEP 1: Understand the UML Diagram
STEP 2: Build the Inheritance Hierarchy
Build the class structure shown in the UML diagram. Remember to include getters and setters for each class
attribute.Create a project called "CIS247B_WK7_Lab_LASTNAME"
STEP 3: Implement Logic for HotRod Class
1. Hint: To generate a random number, use the following code, which returns a random number from 0 to 1: Provide
suitable logic for the toString method. As always, the toString method should reveal the state of an object.
2. For the isDead method in HotRod, use the logic below to implement the inherited base class abstract method called
isDead.
Random rnd = new Random();
rnd.NextDouble();
STEP 4: Implement Logic for StreetTuner Class
1. Provide suitable logic for the toString method. As always, the toString method should reveal the state of an object.

2. For the isDead() method in StreetTuner, use the logic below to implement the inherited base class abstract method
called isDead.
STEP 5: Construct the Main Program
Create an array of Racer objects that will hold three Racer objects.Hint: When completing the Main Class for your lab,
feel free to reuse old methods from previous labs!
1. Write a method, called collectRacerInformation that accepts as an argument a Racer object, and then prompts the
user to provide the following information for each racer.
Racer name
Racer Speed
Number of cylinders in the racer's engine
Horsepower of the racer's engine
2. Add logic to collectRacerInformation to determine if the Racer object passed in is a HotRod or a StreetTuner. If it is
a HotRod, prompt the user to indicate the existence of a blower. If the object is a StreetTuner, prompt the user to
indicate the existence of nitrous. Set these values appropriately.
3. Write a method called displayRacerInformation that accepts as an argument a Racer object, and then displays all
the information for the specific racer type.
4. Create any combination of Racer objects (make sure you create at least one StreetTuner and one HotRod) and
invoke collectRacerInformation, passing in each of the Racer objects. Store each object in the array. For StreetTuner
objects, be sure to set the nitrous flag (either true or false), and for the HotRod objects set the blower flag (either true
or false).
5. Iterate through the racer array and, for each Racer object, display all the object's attribute information (call the
displayRacerInformation method for each object). Don't forget to indicate whether or not the Racer is dead!
STEP 6: Compile and Test
When done, compile and execute your code, and debug any errors until your code is error-free.
Check your output to ensure that you have the desired output, modify your code as necessary, and rebuild.
Your code may resemble the following:
