SecondThingsSecond

Hey, what's that new folder .settings thing for?

Eclipse is a program that has many things that you can customize in it. Some of those customizations are stored in the file org.eclipse.jdt.core.prefs in this folder. These settings are specific for this SecondThingsSecond project and won't always be set the same way for other projects. This file is not intended for people to change directly. Instead, you make changes to menus and dialog boxes in Eclipse, and Eclipse writes out this file.

So, why wasn't it in the FristThingsFirst project?

When I made the FirstThingsFirst project, I was using the default settings for all of the customizations and there were no customizations to store. As I've been working on the SecondThingsSecond project, I wanted to have things configured in a way I'm more used to and a way I think is easier to read.

In the mean time, you might recognize the file in the source folder as the file from the FistThingsFirst folder. We're going to be expanding it in this lesson. In particular, we're going to be adding a game.
