Java is a language that I like the language specification, but the drawback is that it doesn't have a package manager like Python's pip. It takes a lot of time to try it casually as a hobby. However, recently it has become possible to easily build a development environment with a tool called SDKMAN. I will try to install it. Try to install it by referring to the following blog. reference: blog.beaglesoft.net Try setting up Java environment development environment with SDKMAN
$ curl -s "https://get.sdkman.io" | bash
Start the following command in the terminal. However, the development environment of the reference source seems to be Mac, but note that the source destination is slightly different because this is Ubuntu.
$ source "/home/{user}/.sdkman/bin/sdkman-init.sh"
$ sdk help
If you get help information, this is fine. I will investigate and write what to do from now on.
