How can i run java files on glitch ??
Only Node.js is supported - server-side javascript - and serving static pages - HTML, CSS and client-side javascript (which is entirely different to java).
It is possible though, you can try remixing https://glitch.com/~java-spark
Hi @ahmedsaid2019, welcome to the Glitch forum!
As @drew notes only the Node.js ecosystem is officially supported, but your Glitch project is just a container, so whatever you can run on a basic Linux install should work fine: javac HelloWorld.java should do what you expect it to. Language support on Glitch: a list gives a few additional details more generally.
