What does this function "%" do in JAVA? I know it some sort of mathematical function but I am completely confused by it. I am beginner at JAVA so please explain and use an example if you can.

The modulus, or the remainder.
For example, 32 % 10 is 2, the remainder if you divide 32 by 10. 8 % 3 is 2.
One great way to find out if an integer divides evenly is to check the modulus and find out if it's zero. So if X % Y is zero, X is divisible by Y. Let's say you have a four-digit year and want to display the last two digits. In the early days of programming you could say "year - 1900" but that stopped working after Y2K and was one of the sources of Y2K bugs. 2006 comes out as 106, not 06. But "year % 100" gives the right answer.
Good luck.

Hope this helps. It is the same as Java except use System.out.println() instead of the printf() statements.

I beleive it determines the remainer of devision between two integers.

It's the modulous operatior and gives you the remainder when you do division.
