== JDK options ==
Your default choice should probably be to install <code>jdk11</code>, which is an alias for <code>openjdk11</code>. If you're in a server environment, go for <code>jdk11_headless</code>. Java 11 is the currently-maintained LTS version of OpenJDK as of Oct 2019.
As you might expect, though, many flavors of Java are available in NixOS.
* OpenJDK, by far the most popular non-Oracle JVM implementation
** <code>openjdk8[_headless]</code> for a legacy Java 8 VM required by some older apps
** <code>openjdk11[_headless]</code>, the currently-supported LTS version of OpenJDK
** <code>openjdk12[_headless]</code>, the current version of OpenJDK
* AdoptOpenJDK, prebuilt binaries for OpenJDK
** <code>adoptopenjdk-bin</code> points to the latest version of AdoptOpenJDK, which is version 11 at the time of writing.
** <code>adoptopenjdk-jre-bin</code> is available if you want to avoid downloading the compiler and only require the runtime environment.
* JetBrains JDK (<code>jetbrains.jdk</code>), a fork of OpenJDK with modifications made by JetBrains
* Oracle's JDK (<code>oraclejdk</code>), only version 8 is available.
