I NEED help understanding how to declare an instance variable of type Map that will map Items to GameObjects. Initialize the map in a constructor using a HashMap putting the following Game objects in it (WOLF, GOOSE, BEANS, FARMER). Then use that map to be placed in 3 different methods: getName, getLocation and getItem.

Here is ALL of the necessary code:

GameEngine.java

package river;

public class GameEngine {

public enum Item {

WOLF, GOOSE, BEAN, FARMER;

}

public enum Location {

START, FINISH, BOAT;

}

private GameObject wolf;

private GameObject goose;

private GameObject bean;

private GameObject farmer;

private Location currentLocation;

public GameEngine() {

wolf = new Wolf();

goose = new Goose();

bean = new Beans();

farmer = new Farmer();

currentLocation = Location.START;

}

public String getName(Item id) {

switch (id) {

case WOLF:

return wolf.getName();

case GOOSE:

return goose.getName();

case BEAN:

return bean.getName();

default:

return farmer.getName();

}

}

public Location getLocation(Item id) {

switch (id) {

case WOLF:

return wolf.getLocation();

case GOOSE:

return goose.getLocation();

case BEAN:

return bean.getLocation();

default:

return farmer.getLocation();

}

}

public String getSound(Item id) {

switch (id) {

case WOLF:

return wolf.getSound();

case GOOSE:

return goose.getSound();

case BEAN:

return bean.getSound();

default:

return farmer.getSound();

}

}

public Location getCurrentLocation() {

return currentLocation;

}

GameObject

package river;

import river.GameEngine.Location;

public class GameObject {

protected String name;

protected Location location;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public Location getLocation() {

return location;

}

public void setLocation(Location loc) {

this.location = loc;

}

public String getSound() {

switch (name) {

case "Wolf":

return "Howl";

case "Goose":

return "Honk";

default:

return "";

}

}

}
