2. Retrieve the names of the precinct files from reporting.in and as you read each precinct file name, open the corresponding file (precinct#.in) record the votes, and close the file.

I was thinking as I read it line from line, store each letter into an array element, and compare the index of the princinct number with an interger (switch?) and open the coresponding file. Is there an easier way?

reporting.in said:

precinct3
precinct1
precinct4
precinct0

(I have to assume that I do not know that princint2 is not used. It is a general program.

Use a while loop to scan through the data until the end of the file, and store the data in an array...Or if you (theoretically) don't know the amount of precincts in the .in file, then store them in an ArrayList or something.

Create a File object that will be read.

Loop through the array that holds the file names.

File file;
int candidate1 = 0, candidate2 = 0;

for (int x = 0; x < SIZE_HERE; x++)
{
    file = new File(array_or_ArrayList_member_here);

    // read data, compare it to figure out who the vote is for.
}

Sorry if I was unclear at all, I'm in C++ class.

Hope this helps!

That looked Chinese to me. I know there's a While (file.hasNext) thing, but I know that there is 5 princints. And your answer didn't solve my problem. Thanks for the help, but...

So you know for a fact that there are always going to be 5 precincts...

I'll do the best I can, since I don't know the format that your precinct files will be in.

public class Votes
{
    public static void main(String args[]) throws IOException
    {
        File inputFile = new File("reporting.in");
        String[] precinctNames = new String[5];
        Scanner file = new Scanner(inputFile);
        
        int count = 0;

        while (file.hasNext() && count < 5)
        {
            precinctNames[count] = file.nextLine();
            count++;
        }

        for (int x = 0; x < precinctNames.length; x++)
        {
            inputFile = new File(precinctNames[x] + ".in");
            file = new Scanner(inputFile);

            // use the Scanner to read in the votes and tally them
            // to the corresponding candidate.  I don't know the format
            // of the file(s), so this is the best I can do.
        }
    }
}

Hope this clears it up!
