title: How to use javac 1.7 instead of 1.6?
body: <p>I am compiling some java code using javac 1.6.</p>
  
  <p>A large number of errors are generated for multi catch exceptions. This had no problem in java 7.</p>
  
  <p>On running from command line I want to use javac 1.7 instead of javac 1.6 currently being used. How can I achieve it?</p>
  
  <p>(JDK 7 is installed in my computer)</p>
