It compiled and it is still wrong

My loop misses the last item, or one too many

This page is part of Intro to Java with Greenfoot. It assumes you have reached lesson 5.2. Opening it is not counted against you and is not tracked as progress.

What it actually means

The loop boundary is off by one. Either it stops too early and misses an element, or goes one past and throws.

The usual causes

Ranked by how often each one turns out to be the answer. Work down the list.

1. Using a hardcoded size that no longer matches the array.
2. Starting at 1 instead of 0, which silently skips the first element.
3. Using <= where < was needed, which goes one past the end.
