Examples of Predictor

it.sauronsoftware.cron4j.Predictor
A predictor is able to predict when a scheduling pattern will be matched.

Suppose you want to know when the scheduler will execute a task scheduled with the pattern 0 3 * jan-jun,sep-dec mon-fri. You can predict the next n execution of the task using a Predictor instance:
```
 String pattern = "0 3 * jan-jun,sep-dec mon-fri"; Predictor p = new Predictor(pattern); for (int i = 0; i < n; i++) { System.out.println(p.nextMatchingDate()); } 
```
