It compiled and it is still wrong

I changed my code and nothing happened

This page is part of Intro to Java with Greenfoot. It assumes you have reached lesson 1.2. Opening it is not counted against you and is not tracked as progress.

What it actually means

The running scenario is still using the previous version of your code.

The usual causes

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

1. You did not compile. Hatched stripes on the class diagram mean exactly this.
2. You edited a different class from the one in the world.
3. You pressed Run without pressing Reset, so the old objects are still there.
