ghousemohammeditpro/HelloWorldDockerImages-DifferentRuntimes ? reverse-engineered prompt

Build me a small set of Hello World apps that each run in Docker, one for Java, one for Node.js, and one for Python.

I want each version to be very simple, just enough to print a friendly Hello World message or serve a basic response, and each one should have its own folder so they are kept separate. Make sure each app can be built and run easily with Docker, with clear instructions in the repo for how to build the image and start the container for each runtime.

Keep it clean and beginner friendly, since this is mainly for showing how the same tiny app can be done in different languages. If you need to check current best practices for the Docker setup or the latest runtime docs, go ahead and look them up online.
