February 9, 2024 -

Hello there

Are you guys aware of any good online JAVA IDE that supports coding suggestions and error corrections highlighting like Visual studio code?

I have very old Macbook pro (2011 edition) that does not support latest Visual studio code and as Im trying to learn Java on my own, I am looking for any online alternatives for writing and testing any java code or program that works just as well as Visual studio code.

Thank you in advance and have a good weekend.

once this man gets a new computer and installs intelliJ his head is going to explode

Install Linux. I have also a 10 years old Lenovo with Ubuntu and I use Intellij and Visual Studio Code without problems.

r/Compilers on Reddit: Any free, or cheap, online compilers for Python and Java?

October 13, 2023 -

I'm trying to make an online editor and compiler for my students to run code on. Yes, there are some out there but they don't fit my needs.

I've been able to use OneCompiler's API through RapidAPI but it costs a bit too much. Is there an open source compiler I can run on a server and connect to? I've tried use Codex-API but can't get the darn thing to work. It needs me to setup a docker container and such but I get errors. Not sure if it's a me thing or not so I'm looking for guidance from y'all with other possible solutions that I might be missing. Thanks.

Not a compiler but it seems like you are trying to make a version of repl.it
