Struggling with getting my could to test out correctly and I'm not sure what I'm doing wrong:

My Code:

import org.junit.jupiter.api.Test;

class ClassTester {

@Test

void test() {

Traveler t = new Traveler();

Traveler t2 = new Traveler("Jay", Location.EARTH);

assertEquals(t2.current,Location.EARTH);

SpaceShip s = new SpaceShip();

s.setCurrent(Location.EARTH);

s.setCapacity(5);

s.setDestination(Location.RING);

s.setName("Millennium Falcon");

System.out.println("Ship: " + s.getName() + " Current Loc: " + s.getCurrent() + " Destination Loc: "+ s.getDestination() + " Number of Passengers" + s.getCapacity());

SpaceShip s2 = new SpaceShip("Millennium Falcon", Location.EARTH, Location.MARS, 5);

assertEquals(s2.current, s2.destination);

}

Overview

You will be creating a the start of replay system that allows replaying events from a SciFi series. This project specifically focuses on using multiple classes and is therefore larger than the previous project, please try to plan accordingly.

Program Requirements

Location class - the class for identifying the four Locations:

The location are EARTH, BELT, MARS, RING.

Instance Variables

name - the name of the Spaceship. ii. capacity maximum number of travelers allowed on the spaceship

current current location of the spaceship

numOfTravelers actual number of Travelers on spaceship, partially filled array value initialize to zero.

travelers array that contains Traveler Objects that have boarded the spaceship vi. destination destination location of the spaceship

Constructors

public SpaceShip() - default constructor setting name, current and destination to null, capacity to 10 and creates the travelers array and sets size to capacity.

public SpaceShip(String name, Location current, Location destination, int capacity)

1. sets instance variables to matching parameter value

2. creates the travelers array and sets size to capacity.

Methods

Accessor methods for all instance variables as describe in UML class diagram above. (No accessor or mutator for collections such as Arrays!!!!)

No mutator method for numOfTravelers as this is our partially filled array value. iii. boolean board(Traveler t) travelers board the spaceshipIf spaceship is not full (at capacity) and the traveler is not already on board

add traveler to array

increment numOfTravelers

return true.

If spaceship is full or traveler already on board, return false.

static Variable - int nextIDNum - starts at 0 and is used to generate the next Travelers id. b. Instance Variables

name - the name of the traveler. ii. id - id number of traveler

iii. current current location of the traveler

c. Constructors

public Traveler() default constructor setting name and current to null and the id to the next id number

public Traveler(String name, Location l)

Sets name and location to parameter value

Sets id instance variable to next id number.

d. Methods

set/get methods according to the diagram

Remember in setId method use nextIDNum to determine new ID number.

public String toString()

returns a nicely formatted String (see below) that represents the state of the object (the value of the instance variables)

Traveler [name=Klaes Ashford, id=3, current=BELT]

Instance Variables:

name - the name of the Spaceship. ii. capacity maximum number of travelers allowed on the spaceship

current current location of the spaceship

numOfTravelers actual number of Travelers on spaceship, partially filled array value initialize to zero.

travelers array that contains Traveler Objects that have boarded the spaceship vi. destination destination location of the spaceship

Constructors

public SpaceShip() - default constructor setting name, current and destination to null, capacity to 10 and creates the travelers array and sets size to capacity.

public SpaceShip(String name, Location current, Location destination, int capacity) 1. sets instance variables to matching parameter value

2. creates the travelers array and sets size to capacity.

Methods

Accessor methods for all instance variables as describe in UML class diagram above. (No accessor or mutator for collections such as Arrays!!!!)

No mutator method for numOfTravelers as this is our partially filled array value. iii. boolean board(Traveler t) travelers board the spaceshipIf spaceship is not full (at capacity) and the traveler is not already on board

add traveler to array

increment numOfTravelers

return true.

If spaceship is full or traveler already on board, return false.

Travelers are exclusively identified by their ID!

iv. boolean leave(Traveler t) travelers leave the spaceship

If traveler is on-board, in the array, remove them and return true.

If not on-board, do nothing and return false.

v. boolean isOnBoard(Traveler t) checks if a traveler is on-board.

1. returns true if passenger on-board 2. returns false is passenger not on-board.

3. Called a Predicate method (Hint may be used in others methods above to keep code modular)

vi. void move()- moves the ship to its destination

sets the ships current location to its destination.

sets the destination to null

sets all travelers locations to the current location of the spaceship

removes all travelers from the spaceship (array)

vii. public String toString()

returns a nicely formatted String (see below) that represents the state of the object (the value of the instance variables)

Spaceship [name=Behemoth, current=RING, destination=null, capacity=20, passengers=0]

SpaceShipTester class with a main method:

A text-based driver program that performs the following steps:

It asks for four Travelers and two StarShips (Part 1, below)

It executes a text-menu with the following options (Parts 2-4 below)

Add traveler to a Spaceship

Search for traveler on a Spaceship

Move a spaceship to a new location

Exit the program
