I'm using Eclipse - it's free.
Because I'm still learning and doing miniscule taks my needs are very basic.
Actually a text editor with syntax highlighting would be sufficient if I could do debugging with it.

But when you go to eclipse.org the leanest bundle they offer for download are Eclipse Classic and Eclipse IDE for Java developers.
So I downloaded and started the program.
The first thing that greeted me was a dialog that said EGit couldn't find the Git installation.
And I was like double-u tee eff.
I don't need a DVCS to follow my tutorials and exercises and I certainly don't want it.
And it comes with a lot of other stuff, of which I'm not even sure what it is.
I checked the installed plugins and there were like a brazillion entries.

So I googled a bit and found this very helpful tip:

Go to the Platform Project's download area. You want the "Platform Runtime Binary" (49.5 MB) and the "JDT Runtime Binary" (24MB).
Extract and run the platform, go to Help -> Install New Software. Click "Add..." -> "Archive" -> choose the JDT zip you downloaded. Uncheck "Group Items by category", then select the "Eclipse Java Development Tools". Click next to install and restart eclipse when prompted.


I did this and now I have a pretty lean installation of eclipse. Just what I wanted.
Maybe this tip is helpful to someone else.
