COMPLETING THE PLANNER CLASS(25 marks) The int planTrip(int numPassengers, String tripType, Date date, int comfortLevel) method of Planner plans an trip of a given type with the specified number of passengers on the specified date. Steps include: a. Determine the set of buses that the promoter can afford b. Find the lowest cost Bus from the set of affordable buses that i. can hold the number of passengers and ii. is available c. If there is at least one Bus that meets the requirements i. Create an instance of a Trip ii. Call the reserve method of the Bus and capture the return value in an integer iii. If the return value is greater than or equal to 0, 1. Call the setBus method of the trip to the selected bus 2. Pay for the selected bus 3. Return the return value as the result of planTrip d. If plans for the trip did not work out, return -1

pay attention to the bus class and use the methods that might be useful like maybe can hold(im not sure)
