Detect usernames out of array

Dear Community,

I'm trying to get it working, to load usernames out of an array and kick those, who are not on the 'List'. But i get an error in the with '*' marked part...

Code:

@EventHandler
    public void onPlayerJoin(PlayerJoinEvent event)
    {
        Player eventPlayer = event.getPlayer();
       
        String[] Username = {"Name1", "Name2"};
       
        *if (eventPlayer.getName() == Username)*
        {
            System.out.println(eventPlayer.getDisplayName() + " logged in.");
        }
       
        else
        {
            eventPlayer.kickPlayer("You're not on the Whitelist!");
        }
       
    }

Can anyone please help me?

Thanks for your fast answer!

 

When comparing strings in java, always use .equals() or .equalsIgnoreCase()

If I was you, instead of using String[] I'd use a List<String> and then you can just do variable.contains(name)

 

do it inside an PlayerLoginEvent so there is not inside the game that the player has joined

 

If you have a non-trivial number of users in the list, it's better to use a Set. .contains() is much faster on a Set than it is on a List.
