Java. Please review my code below: I have the following errors and not sure how to handle them. Thank you.

First error: has to do with my array: I get the following error: The type of the expression must be an array type but it resolved to Traveler

Second: line 101 error : Multiple markers at this line

- The type of the expression must be an array type but it resolved to Traveler

- The type of the expression must be an array type but it resolved to Traveler

Third: line 132 error: duplicate local variable

Here is my code:

public class SpaceShip

{

private String name;

private int capacity, numTravelers;

private Traveler Collection;

private Location current, destination;

//no argument constructor

public SpaceShip()

{

current = null;

name = null;

destination = null;

capacity = 10;

Collection = new Traveler(capacity);

numTravelers = 0;

}

//parameterized constructors.

public SpaceShip(String name)

{

this.name = name;

current = null;

destination = null;

capacity = 10;

Collection = new Traveler(capacity);

numTravelers = 0;

}

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

{

this.name = name;

this.current = current;

this.destination = destination;

this.capacity = capacity;

Collection = new Traveler(capacity);

numTravelers = 0;

}

//accessors.

String getName()

{

return name;

}

int getCapacity()

{

return capacity;

}

Location getCurrent()

{

return current;

}

Location getDestination()

{

return destination;

}

//mutators.

void setName(String name)

{

this.name = name;

}

void setCurrent(Location current)

{

this.current = current;

}

void setCapacity(int capacity)

{

this.capacity = capacity;

}

void setDestination(Location destination)

{

this.destination = destination;

}

//board method

boolean board(Traveler t)

{

if(numTravelers

{

Collection[numTravelers++] = t;

return true;

}

return false;

}

//leave method.

boolean leave(Traveler t)

{

for(int i=0;i

{

if(Collection[i].getID() == t.getID())

{

for(int j=i; j < numTravelers-1; j++)

Collection[j] = Collection[j + 1];

numTravelers--;

return true;

}

}

return false;

}

//isOnBoard method.

boolean isOnBoard(Traveler t)

{

for(int i=0; i < numTravelers; i++)

{

if(Collection[i].getID()==t.getID())

return true;

{

return false;

}

}

}

//move method.

void move()

{

current = destination;

destination = null;

for(int i=0 ;i < numTravelers; i++)

{

Collection[i].setLocation(current);

for(int i = 0 ;i < numTravelers; i++)

{

Collection[i] = null;

numTravelers = 0;

}

//toString method which overrides the predefined method.

@Override

public String toString()

{

return "SpaceShip[name="+getName()+", current="+getCurrent()+", destination="+getDestination()+", capacity"+getCapacity()+", passengers="+numTravelers+"]";

}

}

This is my other Class Nor errors here:

enum Location {

EARTH, MARS, BELT, RING;

}

class Traveler {

private static int nextIDNum;

private String name;

private int id;

private Location current;

public Location getCurrent() {

return current;

}

public void setCurrent(Location aCurrent) {

current = aCurrent;

}

// constructor to set name and location

public Traveler(String aName, Location aCurrent) {

super();

name = aName;

current = aCurrent;

setId();

}

public Traveler() {

super();

}

public String getName() {

return name;

}

public void setName(String aName) {

name = aName;

}

public int getID() {

return id;

}

public void setId() {

id = ++nextIDNum;

}

// toString to return object data

@Override

public String toString() {

return "Traveler [name=" + name + ", id=" + id + ", location=" + current.name() + "]";

}

}
