Just go to https://openjdk.org/ and click on the "download" link.

Or use your OS package manager and <pkgManager> install openjdk. Problem solved.

Just like any other software, you know ?

That download link takes you to jdk.java.net, which hosts OpenJDK builds built by Oracle.

		I don't get it, what is wrong with that ? Those are OpenJDK binaries and also explicitly named as such not Oracle JDK binaries.
