Question: /* * Spaceship Class 2. Additional instance variable flightHours int representing the number of flight hours of the last flight rounded to the nearest int.
/*
* Spaceship Class
2. Additional instance variable
flightHours int representing the number of flight hours of the
last flight rounded to the nearest int.
3. Methods
1. Default constructor sets all instance variables to a default value
include new instance variables.
2. Parameterized Constructor
2.1. Takes in all parameters required to set the instance
variables.
3. move method same functionality as Project 2 with the following
modification
3.1. boolean method
> returns true if moved allowed
> returns false if moved not allowed.
> Travelers on board are updated by calling the move
method with the parameter this.
4 public String toString()
returns a nicely formatted String (see below) that represents the
Spaceship object information as well as a list of all Travelers.
Spaceship [name=Behemoth, current=RING, destination=null, capacity=20,
travelers=10, flighthours = 20]
It additionally contains a list of all Travelers on the flight (Hint: call
the toString on each Travelers object in the array)
Crew [name=Susan Ivanova, id=3, current=BELT, position =
Captain, pay = $234.00, flight hours = 6728]
Passenger [name=Klaes Ashford, id=3, current=BELT,
seat=FIRST, cost = $1499.99, rewardsPoints = 3459]
