Solved getOnlinePlayers Error

Hey, I'm attempting to make a healing plugin but whenever I type in this code:
for (Player playerToHeal : Bukkit.getServer().getOnlinePlayers()) {
It crosses out the ".getOnlinePlayers" part, it says "The method getOnlinePlayers() from the type Server is deprecated" which I don't know how to fix because I'm fairly new to coding. Here's my code:

Code:

boolean playerFound = false;
               
                for (Player playerToHeal : Bukkit.getServer().getOnlinePlayers()) {
                    if(playerToHeal.getName().equalsIgnoreCase(args[0])) {
                        playerToHeal.setHealth(20.0);
                        playerToHeal.sendMessage(ChatColor.GREEN + "You have been healed be " + player.getName() + "!");
                        player.sendMessage(ChatColor.GREEN + playerToHeal.getName() + " was healed succeessfully");
                        playerFound = true;
                        break;
                    }
                }

it is deprecated, if you don't know what it is, then learn a bit more java. It means, that it will probably be removed in the future.

 

Is there any way to fix this? Should I try updating my external Jar build path file?

 

*facepalm* No, you can use this, there is no problem with that, but be aware, that it can be removed in 1 of the future spigot updates (because bukkit is apparently not in developement). And still, learn java

 

Oh ok thank you, and sorry I'm very new to coding xD

 

Then learn java, and don't do bukkit before that. It is essential for it.
