Hi TheDon_P.. sorry to use your post to get in contact with you, but this app still needs a way of sending private message...

Anyway, I saw your code and found two bugs. This is the fixed code: http://www.sololearn.com/app/sololearn/playground/cBiSb1s3Q4sQ/

The first problen was on the condition of the for loop in the reverseArray method.. it should iterate until the index goes less than zero.

The second problem that arised was that reverseArray didn't have to return anything, or at least doesn't need to return a element of the array already printed on the screen. S, I change the return type to void and remove and removed the return statatement. You could also leave the int return type but then you should return 0;

Hope it helps and sorry to change the topic of your post.

int maxLines = 2;
for (int i=0; i<Math.min(maxLines, lines.length); i++) {
System.out.println(lines[i]);
}

Hi, it won't compile as "lines" isn't declared. Let it be:

String[] lines = new String[] {"a", "b", "c", "d", "e"};
