Assignment Description

Assignment Details

The Alset Corporation wants to begin marketing electric vehicles (EVs) to customers in the nation of Climatonia. Because the company is brand new, models and options are very limited. The user can only select from one of three types of models, and the only available option is an extra charging cable. Your job is to write a program in Java that will allow employees to see the configurations that are currently available for purchase.

Alset EVs come in three types:

Type 1

: Rear wheel drive, small battery pack (short range)

Type 2

: Rear wheel drive, medium battery pack (medium range)

Type 3

: All wheel drive, large battery pack (long range)

All cars feature four doors and come with a charging cable. Type 1 vehicles are painted green and have no other options. Type 2 vehicles are painted blue and have GPS navigation. Type 3 vehicles are painted red, have GPS navigation, and also have a sunroof.

After meeting with the client, the design team determined the following custom class requirements for this program:

A class called Alset with the following:

• A property called numDoors (integer) with a value of 4
• A property called chargeCable (integer) with a value of 1
• A property called paintColor (String) with a value of Green
• A property called freeCharge (String) with a value of No
• A method called displayInfo() that prints each of these properties on screen like this example: “Number of doors: 4”

A class called Type1 with the following:

• Inherits from Alset class
• This model does not have any additional features

A class called Type2 with the following:

• Inherits from Alset class
• An integer property called gpsNav with a value of Yes
• A method that overrides displayInfo(), adding a line to report the gpsNav property

A class called Type3 with the following:

• Inherits from Alset class
• An integer property called gpsNav with a value of Yes
• An integer property called sunroof with a value of Yes
• A method that overrides displayInfo(), adding lines to report the gpsNav and sunroof properties

When the program runs, present the user with a simple explanation of the program (one sentence), followed by a menu that asks them to enter 1 for Type 1, 2 for Type 2, or 3 for Type 3. Use the Scanner class to process input and use IF/ELSE statements to handle their choice. Once the choice has been made, instantiate a member of the appropriate class, set the correct paint color (if type 2 or 3), then execute the displayInfo() method to display the properties of the vehicle on screen. Once the information has been displayed, the program should end.

Write code comments in both the project class and each of the custom classes to document your program. In your custom classes, use JavaDoc comments to document the features of the class.

NOTE:

The paint color may not be set within the Type2 or Type3 classes.

NOTE:

This program must be submitted as a NetBeans project in a ZIP. Separate files or code are not acceptable.

Assignment Details

Create a Java application called “RateCalculator.” In this application, create a custom class named “Calculator.” In the Calculator class, create a method called “Multiply” which accepts two incoming integer variables. Within the Multiply method, create an integer variable to store the total, then calculate the total based on the two incoming variables. Return the total.

In the project class, within the main() method, declare integer variables named “firstNum” and “secondNum” and set their initial values to any number between 1 and 9. Create an additional integer variable called “output.” Then write code to declare a member of the Calculator class called “myCalc” and then utilize myCalc to call the Multiply method to calculate the result of firstNum times secondNum. Store the result in “output”, and present the result on screen.

Within the Calculator class, create methods similar to Multiply called “Add”, “Subtract”, and “Divide.” Create appropriate logic within these methods, and display their use in the main method of the project class. (These methods will not be utilized when the program runs, but the code must be present.)

Write appropriate in-line comments in both the project class and the Calculator class to explain each line of code in your program.

Summary

:

• Create an application called “RateCalculator”
• Create a custom class with the name and features listed above
• Create methods within the Calculator class to perform the calculations
• Write code in the Calculator class (in the main() method) to execute the methods from the Calculator class

Your deliverable for this assignment is the NetBeans project you created using the steps above (ZIP the whole folder that contains the project).

Note:

There is no user input in this program. The values that will be calculated are the values that you state when you declare “firstNum” and “secondNum”.
