quick question JRE 1

[tictaclam]

Is there any way in java code to find out what version of JRE the user is running?

java -version

I mean in the code itself. I need to determine what version they are running to set a switch in my code.

This code lists all the System properties and their values :

     for (java.util.Enumeration e = System.getProperties().propertyNames() ; e.hasMoreElements() ;) {
		 String n = (String)e.nextElement();
         System.out.println(n +":" +System.getProperty(n));
     }

You will probably want to use this property :

String jrevm = System.getProperty("java.vm.version");

Thanks that's exactly what I needed!
