Question:
Please tell me the Java development environment so that it works under Windows 3.1 and develop accordingly for it.
Answer:
Search Borland for JBuilder 4.0 / 5.0 – works great on Windows 3.1
I'm sure it's lying around in some torrent. If you don’t find it, I’ll post it from my archives, just now I parsed and saw the CDROM with the distribution kit.
Update
After tough trolling @alexlz 🙂 – I doubted something and began to remember my fighting youth. I remember exactly that JBuilder 4/5 worked under Win 95/98 (I could be wrong in the version), under Win 3.1 / 3.11 I won't say anything … I have to try.
