I liked the unenhanced for loop more than the enhanced for loop.

Do you agree?

I agree! I like the old school for loop more too, because, for example, it is easier to use an elements index number and the element simply by doing:

System.out.printf("%d : %s\n", i, friends[i]);

whereas the same code in the for-each loop would be like:

import java.util.Arrays;

System.out.printf("%d : %s\n", Arrays.asList(friends).indexOf(friend), friend);

I use both -- it depends on my application. If I need an iterated integer for some reason, I use the old school for loop. For more basic stuff, I use the enhanced for loop.
