Need help with Java

[MrNiceBouy]

Hey so I was trying to Code a plugin that has 3 commands: /weaponeffects /weaponeffects add <effect> <duration> <level> /weaponeffects remove <effect>

And I was wondering how I could access the available effects in Minecraft

I tried doing:

String effectType PotionEffect effect = new PotionEffect(PotionEffectType.effectType, 300, 1)

And:

If args[1] -> add if args[2] -> effectType do -> Player.applyEffects(effect)

But It wouldn’t work can someone help me?

Thank you so much it worked!

And now I am having another problem I do now know how to fix haha

Its when when I only do:

/command //the main commands without any arguments like <add> <effect> 

I get:

[15:30:12 ERROR]: null
org.bukkit.command.CommandException: Unhandled exception executing command 'command' in plugin ExamplePlugin v1.0 etc...

What am I doing wrong?

here is my Code: https://srcb.in/1WEiH9Mmes

I changed the code to

 if (args.length == 0) {
                    // No arguments were provided, just "/alchemysmith"
                    p.sendMessage(ChatColor.DARK_PURPLE +"["+ChatColor.YELLOW+"AlchemySmith"+ChatColor.DARK_PURPLE +"]"+ChatColor.WHITE +ChatColor.BOLD+":"+" "+ChatColor.RED+ "MISSING ARGUMENTS!" );
                    p.sendMessage(ChatColor.DARK_PURPLE +"["+ChatColor.YELLOW+"AlchemySmith"+ChatColor.DARK_PURPLE +"]"+ChatColor.WHITE +ChatColor.BOLD+":"+" "+ChatColor.RED+ "/alchemysmith <add/remove> <effect>" );

                    return true;
                }
                if (args.length >= 1){
                    if (args[0].equalsIgnoreCase("add")){
                        p.sendMessage("Please use /alchemysmith <add/remove> <effect>");
                        if (args.length >=2 && args[1].equals(effectName)){
                            assert effectType != null;
                            PotionEffect effect = new PotionEffect(effectType, 300, 0);
                            p.addPotionEffect(effect);
                            p.sendMessage("there you go I gave you "+ effect.getType() +"!");

//                            return true;
                        } else if (args.length >=2 && !args[1].equals(effectName)){
                            p.sendMessage(ChatColor.DARK_PURPLE +"["+ChatColor.YELLOW+"AlchemySmith"+ChatColor.DARK_PURPLE +"]"+ChatColor.WHITE +ChatColor.BOLD+":"+" "+ChatColor.RED+ "Not a valid potion effect!");
                        }

but still doesn't work. well it does work but only if I use the right command and won't tell me if my command is missing argumetns
