It's almost the same...except that the first one is more efficient because
it uses one IF statement. Doing a compare operation (IF) causes the
processor to let go of the other pine-lines (in an intel Pentium III there
are 3 pipe-lines).
I am not aware of any code optimalisation in the Java Virtual Machine but it
should be more effecient to use one IF statement.
