 /**
  * This application demonstrates the async method invocation pattern. Key parts of the pattern are
- * <code>AsyncResult</code> which is an intermediate container for an asynchronously evaluated value,
- * <code>AsyncCallback</code> which can be provided to be executed on task completion and
+ * <code>AsyncResult</code> which is an intermediate container for an asynchronously evaluated
+ * value, <code>AsyncCallback</code> which can be provided to be executed on task completion and
  * <code>AsyncExecutor</code> that manages the execution of the async tasks.

- * The main method shows example flow of async invocations. The main thread starts multiple tasks with
- * variable durations and then continues its own work. When the main thread has done it's job it collects
- * the results of the async tasks. Two of the tasks are handled with callbacks, meaning the callbacks are
- * executed immediately when the tasks complete.

- * Java provides its own implementations of async method invocation pattern. FutureTask, CompletableFuture
- * and ExecutorService are the real world implementations of this pattern. But due to the nature of parallel
