Question

4. Consider the following program. public class Fraction { private int numerator; private int denominator; public Fraction (int n, int d) { numerator = n; denominator = d; public Fraction add (Fraction f) return new Fraction (numerator * f.denominator + 1. numerator * denominator, denominator + f.denominator); public Fraction add (int x) { return new Fraction (numerator + x denominator, denominator); public Fraction add (int n, int d) return new Fraction (numerator denominator * d); d+n* denominator, public String toString() { return numerator + "/" + denominator; public static void main(String[] args) { Fraction f1 = new Fraction (1, 2); Fraction f2 = new Fraction (2, 3); Fraction f3 = new Fraction (3, 4); Fraction sums = new Fraction [4]; sums [0] - fl.add(f3); sums [1] - f2.add(f3); sums [2] - fl.add(1); sums [31 - f2.add(3, 3); for (int i = 0; i <= sums.length; i++) { System.out.println(sums[i].toString()); The above program compiles without error; what does it display when it is executed?
