IT2650-Assignment 6 Classes, Objects and Methods Solved

The point of this assignment is to cover a few of the basic principles of classes and objects including the proper use of methods.  

 

The solution for this assignment (at least the one I implemented) can be accomplished by inserting code to determine if a prime number ends in the digit entered by the user.

Using the IDE 

. 

Initial Code & Output
 

Load the following code into the online compiler:

 

 

Please copy the following code into the IDE, compile and run it.

import java.util.Scanner; 

 

class Car { 

     

    public void start () { 

         

        System.out.println("The Car Has Started\n"); 

         

    } 

} 

 

public class MyClass { 

     

    public static void main(String args[]) { 

 

        System.out.println("A06 - Written by Matt Weisfeld\n"); 

         

        String consoleInput = null; 

         

        Scanner console = new Scanner(System.in); 

         

        Car myCar = new Car(); 

 

        System.out.print("Please enter a color (or 'x' to end): \n"); 

     

        consoleInput = console.nextLine(); 

             

        System.out.println("\nYou entered " + consoleInput + "\n"); 

             

        myCar.start(); 

         

        System.out.print("Goodbye!"); 

       

    } 

     

}       
     

This code is an introduction to creating objects and passing arguments to those objects. We will cover much of this in detail later in the course; however, take this opportunity to study the code and determine what is going on.

When you execute the code it will look something like this:

  

Problem
 

Add the constructor for the Car class and add the accessor (getters and setters) methods for the color attribute.

Here is an article I wrote many years ago  on encapsulation which is what accessor methods support.

Here are 5 constraints that you must include in your program.

1)     Include an output statement at the beginning of the program with the assignment number and your name:

A06 – Written by Matt Weisfeld

2)     The constructor must pass a single argument to initialize the color.

3)     When the constructor is called, set the car’s initial color to Green.

4)     Include a loop to change the color until an “x” is entered.

5)     Include a condition to test for the “x” and when found use a break to exit the loop.

6)     Print “goodbye” upon exiting the program.  

Final Output
 

Once completed, your output (in the following test case) should look like this:

Test case: enter Red, Blue, x
