Modify WorkerTester class in such a way it reads from a file (workers.txt) the workers information and stores it in a polymorphic ArrayList called workers (of type Worker). The ArrayList is then passed to a method called statistics() to display the basic information and the received pay for all Hourly paid workers and the average pay of all workers.

Assume that each line in the workers.txt contains information about one worker
If the worker is a salaried worker, the line contains 0 name salary
If the worker is hourly paid, the line contains 1 name hourlyRate numHours
