title: Running JAR file on Windows
body: <p>I have a JAR file named <em>helloworld.jar</em>.
  In order to run it, I'm executing the following command in a command-line window:</p>
  
  <pre class="lang-none prettyprint-override"><code>java -jar helloworld.jar
  </code></pre>
  
  <p>This works fine, but how do I execute it with double-click instead?
  Do I need to install any software?</p>
