Issue
Right now when I use a built in method, it shows me the returns types and nothing else that's useful.
Is there something I can download to make the info from the intellisense more robust?
Javadoc not found. Either Javadoc documentation for this item does not exist or you have not added specified Javadoc in the Java Platform Manager or the Library Manager.
Solution
You need to download the JDK API docs, which you can get from this page.
Then in NetBeans, go to Tools -> Java Platforms -> Javadoc to specify the directory where you downloaded them.
