How to read from file?

Question

I have one file, let's say it contain:
1 2
1 4
2 3
It named "filename.txt"
How to read the data from the file?
Here is example of my code.
byte buf[] = new byte[38];
          try {
               FileInputStream in = new FileInputStream("filename.txt");
               in.read(buf);
          catch (Exception e) {
          System.out.println(e);
          String s = new String(buf);
          //int x = Integer.parseInt(s);
          System.out.print(s);
It can print it out according to the contents of the file. The problem is I want the contents become separate, i mean the first column will be saved into first int array, and the second arrat will be in second integer array. Thus 1st array will contains 1,1,2 and the 2nd will contains 2,4,3. I don't want it in the String format. In my code example is in the string format. Anyway can help me out?
Thanks.

Hi,
Take a look at the sample code below:
BufferedReader in
   = new BufferedReader(new FileReader("file.txt"));
String row = null;
while ((row = in.readLine()) != null) {
    String[] parts = row.split(" ");    //part now contains the two values as strings. Use Integer.parseInt to parse them.
    System.out.println("got row " + row);
