<h2>Install Java <span class="JDK_MAJOR">11</span></h2>

<p>
    Download an appropriate JDK for your operating system. We will be using
    <a target="_blank" href="http://jdk.java.net/11/">OpenJDK</a> for this tutorial.
</p>

<p>
    Once installed, you can use the
    <kbd>java</kbd> command from your command line.
</p>

<p>Check if the correct java version is installed:</p>

<pre><code>
$ java -version
openjdk version "11" 2018-09-25
OpenJDK Runtime Environment 18.9 (build 11+28)
OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)
</code></pre>

<p>
    You need to set the <b>JAVA_HOME</b> environment variable to a JDK <span class="JDK_MAJOR">11</span> installation directory. You can follow 
    <a href="http://www.baeldung.com/java-home-on-windows-7-8-10-mac-os-x-linux">this guide</a> to set JAVA_HOME for your platform.
</p>

    <strong>Note: </strong>
    If you have newer or older versions of Java installed along with JDK <span class="JDK_MAJOR">11</span>, you need to make sure that the JAVA_HOME
    environment variable points to JDK <span class="JDK_MAJOR">11</span>.
