Question

Provide a driver class that demonstrates this Fraction class. The driver class should contain this main method:

public static void main(String[] args)
{
Scanner stdIn = new Scanner(System.in);
Fraction c, d, x; // Fraction objects


System.out.println("Enter numerator; then denominator.");
c = new Fraction(stdIn.nextInt(), stdIn.nextInt());
c.print();

System.out.println("Enter numerator; then denominator.");
d = new Fraction(stdIn.nextInt(), stdIn.nextInt());
d.print();

x = new Fraction(); // create a fraction for number 0

System.out.println("Sum:");
x.add(c).add(d);
x.print();
x.printAsDouble();

x = new Fraction(1, 1); // create a fraction for number 1

System.out.println("Product:");
x.multiply(c).multiply(d);
x.print();
x.printAsDouble();

System.out.println("Enter numerator; then denominator.");

x = new Fraction(stdIn.nextInt(), stdIn.nextInt());
x.printAsDouble();
} // end main


Fraction.java

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.



Sample Output

Enter numerator; then denominator.

4/10
Sum:
82/80
1.025
Product:
20/80
0.25

Enter numerator; then denominator.
6
0
infinity
