In the code below, why am I getting an error in the System.out.println that is inside of class Apple? One inside of main runs fine. Thank you for your help.

Because you didn't call it in a method, you are calling it in a class body, which is illegal.

Another tip: Include all errors you're getting in your post.

It will also work if you simply enclose the statement in braces...

This surprises some people. So as a learning opportunity, can a Greenhorn explain why this works? And what triggers that code to execute?
