The code completion feature

While we're talking about NetBeans, let's quickly go over one other IDE feature. Let's say I wanted to write a new line of code and I'm going to use something from the System library:

Once I've typed System., NetBeans can suggest valid responses for me. Only one of these, of course, is going to be what I'm looking for. The NetBeans compiler has a lot of helpful features such as these. If you're the kind of person who thinks code completion is awesome, go ahead and leave these tools on. We can do this by going to Tools | Options | Code Completion and checking the features that we'd like:

If you'd rather NetBeans behave a little more like a text editor, go ahead and uncheck all the features. 

There we go, lots of housecleaning in this section, but hopefully quick and not too painful.
