Counting Loop and Outputting

**Kristenw17** · April 10th, 2013, 11:31 PM

Alright so I made a program that will count the number of fractions in a file and then output the number of times each fraction appeared. I got
it to count the fraction and output. The problem is that I cannot figure out how to skip printing the same fractions count more than once. For example my code outputs:

5/5 has a count of 1
1/1 has a count of 2
1/10 has a count of 1
1/100 has a count of 1
1/1 has a count of 2

    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);
        }
 
        //variables
        String[]fractions = new String[100];  //will take in the fractions 
        String[]split = new String[2];        //used to split the fractions
        int [] numerator = new int [100];     // store numerators
        int [] denominator = new int [100];   //store denominators
        int count = 0;                        //number of lines in file
        int z = 0;
        int same = 0;                         //number of fractions that are the same

        //the string[]fractions
        while(inputFile.hasNextLine()){
                fractions[z]=inputFile.nextLine();
                count++;
                //System.out.println(fractions[z]);
                z++;
           }
 
        //split the fractions[] into two arrays: nummerator and denominator   
        for(int i = 0; i<count; i++){
            split = fractions[i].split("/");
            numerator[i]=Integer.valueOf(split[0]);
            denominator[i]=Integer.valueOf(split[1]);
 
        }  
 
        //used to compare specific numerator and denominator to the rest of the numbers
        int num;
        int den;
 
        //start off by comparing denominator, and then compares the numerator 
        //of like denominators
        for(int i = 0; i<=count; i++){

            }
            //I am putting this in because I could not figure out why 
            //the first and last fractions were printing a count of 0
            if(same<=1){
                System.out.println(num+ "/" + den + " has a count of 1");
            }else{
                System.out.println(num+ "/" + den + " has a count of "+ same); 
            }
            same=0; 
        }
 
        //output the totals
 
 
    }
