You doesn't quite seem to know all the logic if you can't figure this out, a pseudo code would go something like this.

String[] fruits = new String[] { "Orange", "Apple", "Pear", "Strawberry" };
for (String fruit : fruits) {
// fruit is an element of the `fruits` array.
}

The logic of for vs foreach is basically the same the only difference can be the performance of the iteration, traditionally people will say foreach is a little faster.
