COTE: Include internal documentation in your code, if you are not sure, read hapter 2.4 in your textbook and talk to your lecturer Before starting the exercises, make sure you have read the relevant material. 1. Write a class called Fraction.java; this class will be designed to handle fractions. The Fraction class has only two instance variables: An integer numerator An integer denominator The two instance variables can be publicly accessible (at this stage). Supply an input method for the Fraction class: this method will be used by the client to 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 1 ICT167 Principles of Computer Science 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 dont make the methods too much complicated just make them simple
