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

Remember that all code must be submitted in text format.

Initial Code & Output

Load the following code into the online compiler:

https://www.jdoodle.com/online-java-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
);

}

}

public class MyClass {

public static void main(String args[]) {

System.out.println(A06 Written by Matt Weisfeld
);

String consoleInput = null;

Scanner console = new Scanner(System.in);

Car myCar = new Car();

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

consoleInput = console.nextLine();

System.out.println(
You entered + consoleInput +
);

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.

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

A06 Written by Matt Weisfeld

• The constructor must pass a single argument to initialize the color.
• When the constructor is called, set the cars initial color to Green.
• Include a loop to change the color until an x is entered.
• Include a condition to test for the x and when found use a break to exit the loop.
• 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
