Complete the following- The int planTrip(int numPassengers- String tri.pdf

Complete the following:
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
look at this bus class code and utilize the methods in order to complete the int planTrip question
here it is to be clear i need you to complete the int PlanTrip i have my attempted below the bus
class so you can use that to guide you please and thanks
