RFR (S) 8233650 : Javadoc for Math.floorMod(int, int) gives wrong example

[Ivan Gerasimov]

Hello!

The javadoc for the method Math.floorMod(int, int) [1] contains an 
inaccuracy.

There are two sets of examples given:  One for the case when signs of 
the arguments are the same and the other for the case when signs of the 
arguments are different.
The second set of examples wrongly contains an example from the first set.

Would you please help review this javadoc-only fix?
