Player Death Event NPE

So I was wondering what was throwing the NPE in my class. This is what my code looks like:

Code:

    @EventHandler
    public void onPlayerDeath(PlayerDeathEvent evt) {
        if (!(chosen.equals(null))){
            Bukkit.getServer().broadcastMessage("someone died");
        }
    }

 

You're checking for a null value on what I assume would be a string?

 

yes, a player name

 

I'm confused what you're even doing

 

Well, in another class, I define the "chosen" variable with a command, then here, I check if it's null (whether the command has been excecuted) if it's not, then it broadcasts the message

 

1SmallVille1 We really can't help you unless you show more of your code

 

All right but the only thing left is me defining variables:

Code:

public class PvPListener implements Listener {
 
public static String chosen = Commands.chosen;
   
@EventHandler
    public void onPlayerDeath(PlayerDeathEvent evt) {
        if (!(chosen.equals(null))){
            Bukkit.getServer().broadcastMessage("someone died");
        }
    }
}

 

If chosen is null, then there will be an NPE because you will be trying to invoke a method on a null object. It should be

Code:

if(chosen == null)

 

1SmallVille1 You should try and initialize the Commands class by doing it like this
public static Commands c;
public PvPListener(Commands c){
this.c = c;
}
then do public static String chosen = c.chosen;

 

but then shouldn't this work also? because this is what I originally had but it threw the same error

Code:

if (chosen != null)

 

If (chosen != null) can never throw a NullPointerException. Be sure if it is really the same by comparing the stack trace and than get the exact line from the stack trace and investigate that, or post it here to get more help.

 

chosen != null is seeing if the pointer object is null. On the other hand, chosen.equals is a method and will throw a NPE if chosen is null.
