The files must be called <LastNameFirstNameProg7.java>. (driver)
[login to view URL] (handles the fractional numbers)
Example: [login to view URL]
[login to view URL]
Ensure you include ALL files required to make your program compile and run.
I would like to see your .java files only.
Proper coding conventions required the first letter of the class start with a capital letter and the first letter of each additional word start with a capital letter.
Basic Requirements
Write a driver and fraction class that performs addition, multiplication, prints the fraction, and prints as a double.
[login to view URL]
Provide a driver class, LastNameFirstNameProg7, that demonstrates this Fraction class. The driver class should contain this main method:
public static void main(String[] args)
{
Scanner stdIn = new Scanner([login to view URL]);
Fraction c, d, x; // Fraction objects
[login to view URL]("Enter numerator; then denominator.");
c = new Fraction([login to view URL](), [login to view URL]());
[login to view URL]();
[login to view URL]("Enter numerator; then denominator.");
d = new Fraction([login to view URL](), [login to view URL]());
[login to view URL]();
x = new Fraction(); // create a fraction for number 0
[login to view URL]("Sum:");
[login to view URL](c).add(d);
[login to view URL]();
[login to view URL]();
x = new Fraction(1, 1); // create a fraction for number 1
[login to view URL]("Product:");
[login to view URL](c).multiply(d);
[login to view URL]();
[login to view URL]();
[login to view URL]("Enter numerator; then denominator.");
x = new Fraction([login to view URL](), [login to view URL]());
[login to view URL]();
} // end main
Note that this demonstration driver does not call the accessor methods. That’s OK. Accessor methods are often implemented regardless of whether there’s an immediate need for them. That’s because they are very useful methods in general and providing them means that future code can use them when the need arises.
[login to view URL]
Write a Fraction class called [login to view URL] that implements these methods:
add ? This method receives a Fraction parameter and adds the parameter fraction to the calling object fraction.
multiply ? This method receives a Fraction parameter and multiplies the parameter fraction by the calling object fraction.
print ? This method prints the fraction using fraction notation (1/4, 21/14, etc.)
printAsDouble ? This method prints the fraction as a double (0.25, 1.5, etc.)
Separate accessor methods for each instance variable in the Fraction class.
