get a fraction (as two separate integer inputs) from the user. The input method
should ensure that the denominator cannot be 0. Supply an output method for
the Fraction class; this method will be used by the client to print out a fraction
(as two separate integers) to the screen.
An output fraction would be in the form:
numerator / denominator
An example: the fraction for a half would be input as 1 for the first input and 2
for the second input. The output should be printed out as 1 / 2.
Once this is done, write a client class program called
TestFraction.java
; this
class is to be used to test your Fraction class. The program should loop around
getting fractions from the user and displaying them to the screen. Stop when
the numerator is negative.
Note that the client program should use the Fraction class methods (via the dot
notation) to read and display fractions. For example,
pseudo-code
to create a
Fraction object and then use the input and output methods:

class TestFraction
public static void main(String[] args)
// create new fraction
Fraction frac = new Fraction()
// use dot notation to access methods
frac.input()
frac.display()
