I'd like to be able to set a property on the JVM using the -D switch. If I do that, can I access it from my code? If yes, how?

@Geo, yes `mykey` can be any string. However, there are a number of properties already defined by default. There's a list of them in the Java documentation at this page. http://java.sun.com/javase/6/docs/api/java/lang/System.html

A:
Apart from System.getProperty, there's also Integer.getInteger and Boolean.getBoolean, if you want to get an integral or boolean value instead. :-)

A:
and as a bonus:
System.setProperty("yourkey",yourValue); //works very well too
allows you to make sure the property is set if you want to test things
