Java Compilation error on Mac
<p>I have been coding with Eclipse and testing the code using Terminal on OS X 10.7.4. When I ran the code with Eclipse, it worked. However, running with terminal gave me the following error:</p>

<pre><code>Exception in thread "main" java.lang.UnsupportedClassVersionError: PacketPrinter : Unsupported major.minor version 51.0

<p>I checked my java and javac version. They are both 1.7. I have been googling but could not find anything.</p>
