parsing line input

Hi,
I'm doing some exercises out of Hill's book Computer Graphics using OpenGL. He demonstrates a simple program for reading in vertex points, two per line, from a file, and does this as simply as:
inStream >> x >> y;
This reads a line like "25 40" and fills both variables. Is there an easy way to do this in Java?
To read a line with one number I ended up with:
x = Integer.parseInt(reader.readLine());
But for two numbers per line I needed to do this:
String pair[] = splitStrings(reader.readLine());
And then afterwards convert each to an integer.
Is there a simpler way to do this?

K, you could maybe use the splitInts() function instead of splitStrings():
Code:| int pairs[] = splitStrings(reader.readLine()); |

Of course! (I see now). I skipped over this possibility because I assumed that the "Ints" in splitInts() referred to the source and not the results.
