this is the previous checkpoint, please according to theprevious one

Start o point 2 The Tasks A veterinary clinic may want to process its current Wombat queue in the order of severity, i.e. more severe Wombats (higher severity value) are processed first. A PriorityQueue can be used to automatically sort the queue based on the priority of severity 1. Change the implementation of the woueue variable to be a PriorityQueue. Run you code. You should get an error in the output window similar to Exception in thread “main” java.lang.classCastException: practicalD3vets Wombat cannot be cast to java.lang.
