How are you able to specify if the increment is positive or negative with the new school for loop?

The old school for loop had (initialization, termination, increment). This level of specification seems to be hidden here.

Basically you can't. In the for each loop you traverse all of the elements of an array or collection, starting with the first element and going through to the last.

If you want to go backwards you need to use the other for loop, which gives you more control over where you start, where you end, and the size and direction of the increment.

You must be talking about the "for-each" loop. for (int i : intArr[]){} It's just a shorthand method if you need to do something for each item in an array. Otherwise just use the regular for loop if you need to specify more detail in the parameters.
