How to print a specific object by field id within an array list of objects? - arrays

Question

I have a Location class that stores multiple location objects, parsed in from a JSON file. At the moment I can print out all locations in the list by using the toString() method. The output looks like this:
http://hastebin.com/eruxateduz.vhdl
This is an example of one of the loctions within the list:
Location [location=null, id=3, description=You are at battlefield of Jerusalem. You are in awe of your surroundings, you see an exit to the west., weight=100, name=Jerusalem, exit=[Exit [title=Hattin, direction=West]]],
But I'm wondering how I can print out a specific location within that list by the field value id, for example the loction with id="2"?
I'm thinking an override toString method could be created to take an input of id, and print the corresponding location object, but not sure how to print by 'id':
if(LocationObject.getId() == "2") {
//do something
}
This is the POJO Location class that stores the objects:
public class Location {
private Location[] location;
private int id;
private String description;
private String weight;
private String name;
private Exit[] exit;
private boolean visited = false;
private boolean goalLocation;
private int approximateDistanceFromGoal = 0;
private Location parent;
public Location[] getLocation() {
return location;
}
public void setLocation(Location[] location) {
this.location = location;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getDescription ()
{
return description;
}
public void setDescription (String description)
{
this.description = description;
}
public String getWeight() {
return weight;
}
public void setWeight(String weight) {
this.weight = weight;
}
public String getName ()
{
return name;
}
public void setName (String name)
{
this.name = name;
}
public Exit[] getExit() {
return exit;
}
public void setExit(Exit[] exit) {
this.exit = exit;
}
#Override
public String toString() {
return "Location [location=" + Arrays.toString(location) + ", id=" + id
+ ", description=" + description + ", weight=" + weight
+ ", name=" + name + ", exit=" + Arrays.toString(exit)
+"]";
}
}

Answer 1

try checking id's
if(LocationObject.getId() == "2") {
System.out.println(LocationObject.getDescription());
}
