How to add four instance methods to the public interface of class 'Fraction'?

Here is what I tried: https://codeshare.io/5Q18b7

Add four instance methods to the public interface of class 'Fraction': an instance method 'getNominator()' which returns the value of the instance variable 'nominator', an instance method 'getDenominator()' which returns the value of the instance variable 'denominator', an instance method 'setNominator' which sets the value of the instance variable 'nominator', and an instance method 'setDenominator' which sets the value of the instance variable denominator'. codeshare 1 class Fraction 2 { Integer nominator; Integer denominator; public Integer setNominator() { return nominator; public Integer setDenominator() { return denominator; public Integer getNominator() { return nominator; public Integer get Denominator() { return denominator; 22 } 23 24 class Main 25 [ 26 public static Fraction createFraction (Integer nominator, Integer denominator) 27 { Fraction result = new Fraction(); result.setNominator (nominator); result.setDenominator (denominator); return result; public static void main(String[] arguments), final Fraction HALF = createFraction (1, 2); final Fraction THREE FIFTH = createFraction (3, 5); System.out.println(toString (HALF)); System.out.println(tostring (THREE_FIFTH)); 41 } public static String tostring (Fraction fraction) return fraction.getNominator() + "/" + fraction.getDenominator(); 45 46 47 48] ]
