POAccess variable in parent class using super(), or an object?

copied!<p>If you need any info or have a link to a solved answer feel free to post it and I will adjust/delete my question.</p> <p>So for an assignment in comp sci I need to access variables in a parent class. I have something like</p> <pre><code>//import anything? public class HW6Fraction extends Fraction{ public HW6Fraction(int num, int denom){ super(); } public Fraction add(Fraction f) { //Add method int num = super().getNumerator + f.getNumerator(); int denom = super().getDenominator + f.getDenominator(); Fraction result = new Fraction(num, denom); return result; } public Fraction subtract(Fraction f) { //Subtract method int num = super().getNumerator - f.getNumerator(); int denom = super().getDenominator - f.getDenominator(); Fraction result = new Fraction(num, denom); return result; } } </code></pre> <p>as the subclass and something like this as the parent class:</p> <pre><code>//Assignment 2 - problem 3, p. 125 /* Add, subtract, multiply, and divide methods to the Fraction class (section 3.8). Also, add two more constructors. One of the constructors will have no parameters; it initializes the fraction to 0/1. The other constructor will have one parameter, representing the numerator of the fraction; the denominator of the fraction will be 1. Write a TestFraction class (similar to the TestAccount class of Section 3.6) that creates two Fraction objects and tests the behavior of all constructors and instance methods in the Fraction class. Logic: Addition - ((numerator of fraction 1 * denominator of fraction 2) + (numerator of fraction 2 * denominator of fraction 1)) / (denominator of fraction 1 * denominator of fraction 2) Subtraction - ((numerator of fraction 1 * denominator of fraction 2) - (numerator of fraction 2 * denominator of fraction 1)) / (denominator of fraction 1 * denominator of fraction 2) Multiplication - (numerator of fraction 1 * numerator of fraction 2) / (denominator of fraction 1 * denominator of fraction 2) Division - (numerator of fraction 1 * denominator of fraction 2) / (denominator of fraction 2 * numerator of fraction 1) */ public class Fraction { private int numerator; //Numerator of fraction private int denominator; //Denominator of fraction public Fraction(int num, int denom) { //Constructor numerator = num; denominator = denom; } public Fraction() { //Constructor w/ no parameters new Fraction(0, 1); } public Fraction(int num) { //Constructor w/ numerator parameter numerator = num; int denom = 1; } public int getNumerator() { //getNumerator method return numerator; } public int getDenominator() { //getDenominator method return denominator; } public void setNumerator(int num) { //setNumerator method numerator = num; } public void setDenominator(int denom) { //setDenominator method denominator = denom; } public Fraction add(Fraction f) { //Add method int num = numerator * f.getDenominator() + f.getNumerator() * denominator; int denom = denominator * f.getDenominator(); Fraction result = new Fraction(num, denom); return result; } public Fraction subtract(Fraction f) { //Subtract method int num = numerator * f.getDenominator() - f.getNumerator() * denominator; int denom = denominator * f.getDenominator(); Fraction result = new Fraction(num, denom); return result; } public Fraction multiply(Fraction f) { //Multiply method int num = numerator * f.getNumerator(); int denom = denominator * f.getDenominator(); Fraction result = new Fraction(num, denom); return result; } public Fraction divide(Fraction f) { //Divide method int num = numerator * f.getDenominator(); int denom = denominator * f.getNumerator(); Fraction result = new Fraction(num, denom); return result; } } </code></pre> <p>These lines are where I am having a problem: </p> <pre><code>int num = super().getNumerator + f.getNumerator(); </code></pre> <p>I wonder if there is proper terminology for this?</p>
