title: Newbie on debian and trying to make Java 7 the default java version used
body: <p>2 questions.</p>
  
  <ol>
  <li>After installing the Oracle Java 7 on my new Debian local box, I opened up a terminal and executed the following command:</li>
  </ol>
  
  <p>java -version</p>
  
  <p>When I did that it states:  java version "1.6.0_26"
  Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
  Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)</p>
  
  <p>I installed the Java 7 JDK and Java 7 JRE in the following directories respectively:  </p>
  
  <p>/usr/lib/jvm/jdk1.7.0
  /usr/lib/jvm/jre1.7.0</p>
  
  <ol>
  <li>Is there a way to remove the java-6-sun and java-6-sun-1.6.0.26 folders as well or will it hurt just to leave them there?</li>
  </ol>
  
  <p>Any help/direction on these 2 questions would be appreciated.</p>
  
  <p>Regards.</p>
