Regex for two real numbers separated by a space [Java]

My code is as follows:

String realNumber = "[+-]?[\\d]+(?:[\\.][\\d]+)?";
s.next(realNumber + "[\\s]+" + realNumber);

Full regex:

[+-]?[\\d]+(?:[\\.][\\d]+)?[\\s]+[+-]?[\\d]+(?:[\\.][\\d]+)?

This doesn't work. If I use s.next(realNumber); it works fine for a single real number, i.e. 321.1 or 12 etc. The space is the part that seems to throw the mismatch exception.

I have been trying to get this to work for the past hour now >.> Please help!

Patterns that should match:

1 1 
1.1 2.1
123 1.123
123.123 1

Thanks,
