Solved Error with player names

I was trying to create a SkyBlock Plugin for my server. When a player types /is go the program checks if the sender has an island. All the islands are stored in a set called islSet. Here's some code

Code:

case "go":                   
if(hasIsland(player) == true) {
                        try{
                            player.teleport(getPlayerIsland(player).mainBlock);
                            player.sendMessage(prefix + "Teleporting to your island");
                        } catch (NullPointerException ex) {
                            player.sendMessage(prefix + "Error teleporting to the island (NullPointerException), talk to a staffer!");
                            System.out.println(prefix + "Error teleporting " + player.getName() + " to the island, [Error] NullPointerException");
                        }
                    } else {
                        player.sendMessage(prefix + "You have no island so you can't be teleported");
                    }

Here i'll post the hasIsland method

Code:

public static boolean hasIsland (Player player) {
        String pName = player.getName();
        for(Island is : islSet) {
            if(is.owner == pName) {
                return true;
            }
        }
        return false;
    }

When the hasIsland method is called, it returns false even when the player owns an island.
The code was originally in Italian but i changed the words to allow everyone to understand. In case I forgot somethings :
proprietario = owner
teletrasportando = teleporting
isola = island
Errore = Error

Don't compare strings with == use .equals instead. You should be using UUID's instead of player names anyway.

 

Thanks now it works perfectly. I'll follow your suggestion of UUIDs
