Thread: File reading issues

So my end goal is to have read a file containing fractions, and be able to count the number of times a specific fraction appears.
Example file:
6/3
7/2
6/3
5/2

So far I have been able to get the program to count the the number of lines. My idea was to us a for loop to take in a line of the file at a time, and put the numbers from the fraction into an array. My problem is that no matter how many different ways i try this it wont work. It keeps outputting null.

import java.util.Scanner;
import java.io.FileNotFoundException;
import java.lang.String;
import java.io.File;
import java.io.FileInputStream;
 
public class Assignment1{
 
    public static void main(String [] args){    
        //Reads file containing fractions
        Scanner inputFile = null;
        try {
            inputFile = new Scanner(new FileInputStream("fractions.txt"));
        }
        catch (FileNotFoundException e) {
            System.out.println("File not found or not opened.");
            System.exit(0);
        }
        fractionCounter(inputFile);
 
    }
 
 
    public static void fractionCounter(Scanner file){
       //variables
        String line;                       // place holder for line
        String[]test = new String[100];   // array that holds fractions
        int count= 0;                     // use to count the number of lines
 
 
       //Count the number of lines in the file
       while(file.hasNextLine()){
           count++;
           file.nextLine();
 
           for (int i=0; i<=count; i++){
               line = file.nextLine();
               test = line.split("/");
            }
           file.nextLine();
       }
 
       line = file.next();
       System.out.println(line);
 
       //for(int i=0; i<=count; i++){
        //    line = file.nextLine();
        //    test = line.split("/");
 
       //}
 
       //for(int i = 0; i <= count*2; i++){
        //    System.out.println(test[i]);        
       //}
    }     
 
}

line = file.next();
System.out.println(line);

I did the print line to make sure that the fractions were in fact filling the array. They are not. I can't figure out how to put the numbers into the array

The error was java.util.NoSuchElementException

No line was found when using file.next()
Scanner (Java Platform SE 7 )

The while(file.hasNextLine()) loop will catch this situation, but I think you need to check the number of times you use next() and nextLine(). Try and simplify it.

Have you thought about how you are going to store, compare and collate the fractions in the array?
