java For this assignment, you need to develop NumberQueue ADT (NumberQueue.java). We assume each number in the queue represent a person in the line waiting for being served at your restaurant. Based on historical data, you found that on average, one customer arrives at your restaurant on every five minutes interval, and it takes 3 minutes to serve each customer. Write a tester program, named QueueSimulation2.java, to simulate the queue for 8 hours, then print the longest queue size during the 8 hours operation longest waiting time, and average waiting time. Did anyone leave your restaurant because the line if full? (assume the maximum capacity of the line is 10 people) . Additional requirements: use thread for enqueue process! Once completed, run your simulation and save your output to results.txt file.
