Thread: Array, fractions, etc

So here is what I am trying to accomplish: I am creating a program with two classes: Fraction and FractionCounter. I am having some major problems (mostly because I am unsure of how to to the basic frame for the program). I am not posting the FractionCounter class because I am just worried about getting the Fraction class working at the moment.

Here is my Driver: I would appreciate any comments on how I can improve it because that is were most of my problems are.
1. I can't figure out the best way to do the driver so that it is possible to use the equals method from the Fraction class.

public class Homework2Driver{
 
   public static void main(String[] args) throws FileNotFoundException{
        Scanner input = new Scanner(new File("fractions.txt"));
 
        String [] fractions = new String[100];
        int size = 0; 
        int [] numerator = new int[100];
        int [] denominator = new int[100];
        String[]split = new String[2];       
        //ArrayList<FractionCounter> counter = new ArrayList<FractionCounter>();
 
        //take a line at a time and put it into a string []
        while(input.hasNextLine()){
            fractions[size]= input.nextLine();
            size++;
        } 
 
        //for loop to split fractions into numerator and denonimator
        for(int i = 0; i < size; i++){
         split = fractions[i].split("/");
         numerator[i]=Integer.valueOf(split[0]);
         denominator[i]=Integer.valueOf(split[1]);
        } 
 
        for(int i = 0; i < size; i++){
         Fraction a = new Fraction(numerator[i],denominator[i]);  
 
        }
   }    
}

Fraction Class: the only thing i'm really concerned with here is the boolean equals method. I know I did not do this right.

public class Fraction{
 
    private int numerator;
    private int denominator; 
 
    public Fraction(){
 
    }
 
    public Fraction(int n, int d){
       setNumerator(n);
       setDenominator(d);
 
    }
 
    public String toString(){
        return String.format("%d/%d", getNumerator(), getDenominator());
    }
 
    public boolean equals(Object otherObject){
        if(otherObject == null){
            return false;
        }else{
            if(!getClass().equals(otherObject.getClass())){
                return false;
            }else{
                Fraction otherFraction = (Fraction) otherObject; 
                return getNumerator()== otherFraction.getNumerator() && 
                       getDenominator()== otherFraction.getDenominator();
 
            }
        }
    }
 
    public int getNumerator(){
        return numerator;
    }
 
    public void setNumerator(int newNumerator){
        numerator = newNumerator;
    }
 
    public int getDenominator(){
        return denominator;
    }
 
    public void setDenominator(int newDenominator){
        if(newDenominator == 0 ){
            throw new IllegalStateException(String.format("Illegal denominator: %d", newDenominator));  
        } else{
            denominator = newDenominator;
        }
    }
 
}
