====== The Basics: Exercise 2 ======

Add another advice to the ''Basics'' aspect to print out a message immediately before the execution of all methods of ''Application'' whose name starts with the letters "st".

<note tip>
Inside the signature pattern, you can use the wildcard ''*'' to match any type or identifier (or any type or identifier with a certain beginning). As part of the argument list, you  can use ''..'' to match any number of arguments.
</note>

Since the advice applies to different methods, print the signature of the join point in the advice body using the following snippet:

<code aspectj>
output("ex2",thisJoinPoint.getSignature());
</code>

<note>
Inside an advice, the reserved variable ''thisJoinPoint'' provides access to runtime information about the join point. It is of type [[http://www.eclipse.org/aspectj/doc/released/runtime-api/org/aspectj/lang/JoinPoint.html|JoinPoint]].
</note>

Rerun the application and verify that the aspect outputs a signature for methods ''start'' and ''stop''.
