 ====== The Basics: Exercise 1 ======
-Create an aspect named ''Basics''.
+Create an aspect named ''Basics'' with an auxiliary method ''output'':
-Inside, write an advice that prints out a string just before the execution of the ''start()'' method. Use the following form for your advice:
+<code aspectj>
+public aspect Basics {
+  public void output(String tag, Object o) {
+    System.out.println(tag + ": " + o);
+  }
+}
+</code>
+Next, add an advice to this aspect to prints a string just before the execution of the ''start()'' method. Use the following form for your advice:
 <code aspectj>
 before(): <pointcut> {
-  System.out.println("About to start");
+  output("ex1","About to start");
 }
 </code>
 <note tip>
-You can employ the primitive pointcut ''execution(//Signature//)''. The signature should at least specify the return type, the method name and the arguments.
