+<p>You'll be shocked at this moment as you have to write down a lot more lines
+ of code than in the classical java method example. But on the other hand
you'll gain

contrac-example.jar:</p>
+ <source>java -jar contract-example.jar</source>
<p>As you can see, you have to define constraints for all the parameters that your
method will accept.
You even have the possibility to provide a default value that will be used
when no parameter value
is provided. This means, that the parameter is optional.</p>
