Substring() equivalent on numbers

Is there an equivalent of substring() on primitive numbers? Given an int = 12345, I would like to extract let's say, 34 from it.

You can first convert your number to a String and then use substring.
int i = 12345;
String s = Integer.toString(i);

But maybe a String would be better from beginning on for your purpose cause this operation makes no sense for a number.

The division (/) and remainder (%) operators can be useful too when doing this sort of thing. And remember that your integer is base 10.
