title: How do I find where JDK is installed on my windows machine?
body: <p><strong>I need to know where JDK is located on my machine.</strong> </p>
  
  <p>On running <code>Java -version</code> in <strong>cmd</strong>, it shows the version as '1.6.xx'.
  To find the location of this SDK on my machine I tried using <code>echo %JAVA_HOME%</code> but it is only showing 'JAVA_HOME' (as there is no 'JAVA_PATH' var set in my environment variables).</p>
