How to install java in NixOS?

Question

On NixOS, I am trying to install java in order to compile my code from the command line.

I do not see the java compiler listed anywhere in the list of available packages, queried by running nix-env -qaP '*' --description.

How do I install a java compiler on NixOS?

This page might help: nixos.org/nixos/packages.html it's a dynamic search page for NixOS' store. — Mio Rin, Nov 11, 2017 at 4:50
Searching using a package name usually useless unless you know what you are looking for. Use package page mentioned above or add --description flag, for example, nix-env -qaP --description | grep -i java\.*devel — wizzup, Nov 11, 2017 at 6:58

There are two Java compilers available via Nixpkgs: OpenJDK and OracleJDK, named openjdk and oraclejdk, respectively.

Note that the OracleJDK doesn't seem to be available in the top-level expression, but you can certainly install the openjdk.

Thank you. I missed openjdk since I had been searching for java.
