Checking if a specific player is online

basicaly i want the command isvitalogonline to say if the player vitalog is online i have tried different ways but if he ISNT online i get an internal error and i dont know why...

Code:java

        else if(commandLabel.equalsIgnoreCase("isvitalogonline")){
            if(player.hasPermission("Legacy.vitalog")) {
                if(Bukkit.getPlayerExact("vitalog").isOnline()) {
                    player.sendMessage(ChatColor.GREEN + "Vitalog Is Online");
                }
                else{
                    player.sendMessage(ChatColor.RED + "Vitalog Is Offline");
                }

 

Code:java

Player target = Bukkit.getPlayer("vitalog");
 
if (target == null){
 
player.sendMessage(ChatColor.RED + "Vitalog Is Offline");
 
}else{
 
player.sendMessage(ChatColor.GREEN + "Vitalog Is Online");
 
}

 

It's because getPlayerExact() returns null if there is no such player. And you CAN'T call methods for null stuff... logic - there is no object. Simply check if getPlayerExact() != null.
