how to make protection for not player spam a command (once a day)

Hello,
Today I have a problem for make a protection for not player spam command I want he runs it once a day,
Thanks.

 

what have you got yet? show some code where you want to implement that

 

I want to implement in the onCommand.

Code:

package fr.ornomas.plugin.commands;

import java.util.Random;
import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.World;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class CommandRtp implements CommandExecutor 
{

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String msg, String[] args) 
    {
        if (sender instanceof Player)
        {
            Player player = (Player)sender;
            World World = player.getWorld();
            Random random = new Random();
            Location ploc = player.getLocation();
            int x = (int) (ploc.getX() + random.nextInt(5000));
            int z = (int) (ploc.getZ() - random.nextInt(5000));
            Location rtp = new Location(player.getWorld(), x, 50, z, 0f, 0f);
            Location rtp1 = new Location(player.getWorld(), rtp.getX(), World.getHighestBlockYAt(rtp), rtp.getZ(), 0f, 0f);
            player.sendMessage(ChatColor.DARK_GRAY +  "Teleportation aleatoire...");
            player.teleport(rtp1);
        }
       
        else 
        {
            System.out.println(ChatColor.DARK_GRAY + "Seul les joueurs peuvent executer cette commande");
        }
        return false;
    }
   
}

(maybe check for the commands name before executing it. If you only have one well ok but its not a good practice)
make a HashMap<UUID, Long> and store the players uuid and the current system's time in there. before executing the random tp check if the last use is already one day ago (upToDateTime - lastTime > 1 day)

 

it's too difficulte for me because i'm bingeener.
you have an idea for the code.

 

@OP

Better to learn how to use a custom config file or otherwise, so that if your server resets/reloads the HashMap isn't cleared.

Write names and local time in the file and everytime they run the command check if it's past 24 hours, or relevant time.
