array help

[dazednconfused]

I am trying to figure out ow to read integers from a user specified file in to an array. Since i don't ave any information about te file except for the fact that it is more or less a matrix, how do I get the program to read those numbers into a multidimensional array ?

You will HAVE to know something about the file. For example, you'll need to know what delimiters are being used, or test for several different ones; i.e. spaces, commas, periods, whatever.

Once you know what type of delimiter is used, you can make a 2d array and then read the input line by line.
For file input, I usually use something like the following:

BufferedReader in = new BufferedReader(new FileReader("myFile.txt"));
String line = in.readLine();
String[] numbersAsStrings = line.split(",");  //creates an array of strings split by the supplied delimiter, in this case a ,
for(int i=0; i<numbersAsStrings.length; i++){
    some2DArray[row][i] = Integer.parseInt(numbersAsStrings[i]);
}

That is an over-simplified example, I'm not checking for errors, and I'm only reading in 1 row. You would need to either make a nested for loop or a while loop that tests for end of file or something like that. I hope it gets you started! :D
