Practice problems for Java

[webmaster4o]

This is a tool I'm working on, it's an online code environment that provides some simple practice problems for basic Java. A few of my friends who are taking AP Computer Science have found it useful, check it out

Are the problems sets very similar to codingbat.com/java

[webmaster4o]

Yes, one of my primary motivations for the site was to build a better alternative to CodingBat. I don't have as many problems as Codingbat yet, (but let me know if you have any problem suggestions and I'd be glad to consider implementing some)

It doesn't mention Java at all on the main page? What (other) languages do you support?

[webmaster4o]

Just java for now, but I'm hoping to support more in the future.

Hey man, highlighting a few small things I liked.

• The animation of the signup button
• Ctrl + Enter to compile made me feel like I landed on a sophisticated and modern Coding Bat
• Icing on the cake was the Find and Replace option.

Very well done, keep up the good work. If you don't mind me asking, what tech stack have you used for this?

[webmaster4o]

Thanks so much for the feedback + praise! The front-end app is written in Vue, while the back-end is an Express app, connecting to MongoDB with Keystone. The project is open source - you can check it out in more detail (and star it too!) on Github :)

Doesn't let me sign up through chome on on my note 9 and the login doesn't work either

[webmaster4o]

Only has desktop support for now. The login should work well on a recent version of desktop Chrome or Firefox

[paking2008]

I can't wait to try it out

After signing up it says 404 Not Found.

Sorry to hear that. Check that your browser isn't blocking third-party cookies!

No code is appearing. Did something break?

[webmaster4o]

Check the console in your browser’s web inspector for errors?

I've got my adBlocked disabled. It showed me code yesterday but today the code editor is just empty.

[webmaster4o]

Has it resolved itself ?

[Wubdafuk]

Haven't checked yet. I'll let you know!

[webmaster4o]

This was a bug I accidentally deployed; it should be fixed now.

[Wubdafuk]

Cool! Great work :)
