make a class to represent an object of type Passenger using the description provided below in UML

Passenger

- name : String

- birthYear : int

- weight : double

- gender : char

- numCarryOn : int

+ Passenger() // Set name="", birthYear=1900, weight=0.0, gender='u', numCarryOn=0

+ Passenger(String, int, double, char, int)

+ calculateAge(int) : int // use birthYear and the argument of currentYear to calculate age.

// If currentYear < birthYear, return -1.

+ gainWeight() : void //increase weight by 1.

+ gainWeight(double): void // increase weight by the input amount. Weight cannot drop below zero.

+ getBirthYear() : int

+ getGender() : char

+ getName() : String

+ getWeight() : double

+ getNumCarryOn: int

+ isFemale() : boolean // return true if gender is 'f'

+ isMale() : boolean // return true if gender is 'm'

+ loseWeight() : void // decrease by 1. Weight cannot drop below zero.

+ loseWeight(double) : void // decrease weight by the input amount. Weight cannot drop below zero.

+ printDetails() : void // prints Passenger attributes in the following format:

// "Name: %20s | Year of Birth: %4d | Weight: %10.2f | Gender: %c | NumCarryOn: %2d "

+ setGender(char) : void // if input value is not 'm' or 'f', set gender to 'u' (unknown)

+ setName(String) : void

+ setBirthYear(int) : void

+ setWeight(double) : void //if input value is negative, set weight to -1

+ setNumCarryOn(int): void //if input value is negative, set numCarryOn to 0, if it is greater than 2 set to 2

Homework 3-2 Textbook Section 8.21

make a class to represent an Airplane object containing instances of the Passenger objects

Airplane

• passengers : Passenger [ ]
• airplaneName : String
• numPassengers : int //calculated controlled variable no setter

• Airplane() //default array length = 100 , numPassengers = 0
• Airplane(String) //default array length = 100 , numPassengers = 0
• Airplane(int) //max size of array, if value is negative set to 0
• Airplane(String, int) //name of airplane, max size of array, if value is negative set to 0

• addPassenger(Passenger) : void
• getAirplaneName() : String
• getPassenger(int) : Passenger //return null if index is invalid
• getNumPassengers() : int //notice no setter... this is a controlled variable
• getFirstPassenger() : Passenger
• getLastPassenger() : Passenger
• getPassengers() : Passenger [ ]
• setAirplaneName(String) : void
• printAllDetails() : void // prints Airplane attributes Passenger attributes as formatted below:

// "AirplaneName: %20s | Number of Passengers: %4d | Airplane Size: %4d "

// "Name: %20s | Year of Birth: %4d | Weight: %10.2f | Gender: %c "

• removePassenger(int) : Passenger
• removeAllPassengers() : void
• getTotalWeightOfAllPassengers() : double
• getAverageWeightOfAllPassengers() : double
• getNumberOfPassengersAboveWeight(double) : int
• getNumberOfPassengersBelowWeight(double) : int
• increaseWeightOfAllPassengers() : void
• increaseWeightOfAllPassengers(double) : void

Homework 3-3

make a Driver class to use your Airplane and Passenger classes and create instances of them.

In the main method do the following:

2. Create an Airplane that will store up to 100 Passengers
4. Create 5 Passenger Objects with the details specified in the table below
6. Add the 5 Passenger objects to the Airplane
8. Call the printDetails method from the Airplane to print all the Airplane and Passenger details.

variable name	name	birthYear	weight	gender	numCarryOn
p1	Albert	1879	198.5	'm'	2
p2	Grace	1906	105	'f'	1
p3	Tim	1955	216.3	'm'	2
p4	Steve	1955	160	'm'	2
p5	Sergey	1973	165.35	'm'	1
