Check if Null, but still internal error plus stacktrace.

So, I am coding a plugin and I check if the player is null but when I run the command on a person online it still says they're null. So, I gave it a message to send if they see that the player they run the command on is null, but it still has an internal error!

Code:

if(args[0] != null){
            
                    Player target = Bukkit.getServer().getPlayer(args[0]);
                
                    sender.sendMessage(Blocking out for secrecy :) );
            
                }
            
                if(args[0] == null) {
    sender.sendMessage( "That player Isn't online!");
                }

 

Don't check if the argument is null, that just means you didn't type anything after the command. Check if the target is null. @S1ant

Example:

Code:

if(commandLabel.equalsIgnoreCase("check")) {
            //Check if the command arguments are 0, meaning if the player only typed "check"
            if(args.length == 0) {
                //Then tell them a correct usage
                p.sendMessage("/check (name)");
                //Else if the player entered the correct amount of arguments which is 1
            } else if(args.length == 1) { //One stands for the first argument (name) in /check (name)
                //Define the target
                Player target = Bukkit.getServer().getPlayer(args[0]); //Please note; this isn't an efficent way of getting a target player
                //Check if the target is null
                if(target == null) {
                    //If null send message
                    p.sendMessage(ChatColor.RED + "Sorry! I can't find " + args[0] + "! I'll grab my glasses next time.");
                    //Message sent, so it worked, return true
                    return true;
                  
                    //Else if NOT null meaning Online
                } else {
                    //Send message
                        p.sendMessage(ChatColor.GREEN + "I found the player!");
                }
            }
        }

 

@DuaneTheDev_ Ok, I looked over the code, but apparently didn't use my common java sense. Thanks!
