Complete the following code based on these instructions :
COMPLETING THE PLANNER class 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
