useDelimiter usage

[reis3k]

Hi I really confused with delimiters. I have a text file which has two number separated by white space on each line. I need first number as a array index and second number for that array's index value. How can I do this. I started my code in this way:

		BufferedReader in = new BufferedReader(new FileReader("data.txt"));
		Scanner s = new Scanner(in).useDelimiter("\n");
		
		String strLine = null;

		
		while (s.hasNextLine()) {
			System.out.println(s.nextInt());
		}

Don't fiddle with those delimeters for now, the default values are adequate because your numbers are separated by white space two of them per line.

Thanks, but I just need the first number on one line firstly as a index number of my array. So in a way I should skip the second number on the line and just see the fisrt numbers on each line. How can I do this?

Do a nextInt() to get your index number and then a nextLine() to read the rest of the line (and discard the return value of that method) then start all over ...

Thanks, now I got the idea. Here is the code:

		while (s.hasNextLine()) {
			//System.out.println(s.nextInt());
			//s.nextLine();#
			puzzle[s.nextInt()]=s.nextInt();
		}
