NetBeans there, NetDone that

It's been more than half a year since I previously wrote about Java. At this speed I'll have written a functioning program by the time I'm in my 80s.

Here's what new for me:

NetBeans. This time I thought I'd have a look at NetBeans. The IDE seems tidier than Eclipse, but that might simply mean that it has less features. I already had it installed since I had tested it with PHP, but now it wouldn't start for some reason.

I had installed NetBeans to /opt/ so I took some time for me to track it down (I don't have much there) and NetBeans wasn't able to find JRE any more (don't know why). When I finally solved that, I couldn't start coding Java until I swapped the JRE path with the path to the JDK. All this took me a while. But I finally got it going.

ClassPath. I also tried to use some libraries, and was unsure about how to go about it. Where should i put them? Turns out I should put them in a classpath, which didn't mean a thing to me. But I think it simply meant that I had to find some place where I'd put all of my own reusable library classes - and those I've downloaded - into a certain place, and right click a project to edit the properties and add the libraries I'll need.
