The Activity2 class does not do any exception checking. Modify it so that you handle any exceptions that could occur. Note that you should not change Fraction.java

public class Activity2 { public static void main(String[] args) { Fraction n = new Fraction(8,3); Scanner scan = new Scanner(System.in); System.out.print ("Enter the numerator: "); n.setNumerator(scan.nextInt()); System.out.print ("Enter the denominator: "); n.setDenominator(scan.nextInt()); System.out.println ("The fraction " + n.getNumerator() + "/" + n.getDenominator() + " is equal to " + n.toMixedNumber()); scan.close(); } }
