The Example class has a main method, which means this class can be executed via the command line. Assuming the Example class was in a package of com.foo, in a directory named out, i would execute with command line arguments like so:

java -cp out com.foo.Example First Last

This would create a User object named "author" with a fist name of "First" and a last name of "Last"

Hope this helps.
