Solved Need help with saving in config

To not create new thread i need help with commandExecutor in the same plugin
1. i don't want console to use "/rb"
2. if there's 1 arg i don't want it to be different from place/break/reset/tool

Code:

package me.miloszgnk.RestoringBlocks;

import java.util.List;

import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.HumanEntity;
import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.command.CommandExecutor;


public class myCommandExecutor implements CommandExecutor {

    private Main main = Main.getInstance();
  
  
    List<Location>    locations = main.getLocationList();
  
  
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
        if (cmd.getName().equalsIgnoreCase("rb")){
            if (!(sender instanceof Player)){
                sender.sendMessage("[RestoringBlocks] You can only use that command in-game");
                return false;
            }

            if(args.length==0){
                sender.sendMessage("====[RestoringBlocks]===");
                sender.sendMessage("/rb - shows menu");
                sender.sendMessage("/rb place - activates placing restoring blocks");
                sender.sendMessage("/rb break - activates removing restoring blocks");
                sender.sendMessage("/rb reset - removes all restoring block");
                sender.sendMessage("/rb tool - gives tool for editing restoring blocks");
                sender.sendMessage("=========================");
            }
          
            if (args.length==1 && args[0].equalsIgnoreCase("place")){
                Player p;
                p = (Player) sender;
                if(main.getRestoring_Blocks_Placing_Activated(p).equals(false)){
                    main.setRestoring_Blocks_Placing_Activated(p, true);
                    sender.sendMessage("true");
                }
                else{

                    sender.sendMessage("false");
                }
                }
            }
          
            if (args.length==1 && args[0].equalsIgnoreCase("test")){
                sender.sendMessage(main.getRestoring_Blocks_Placing_Activated((Player) sender).toString());
            }
      
            if (args.length==1 && args[0].equalsIgnoreCase("break")){
                Player p;
                p = (Player) sender;

                    main.setRestoring_Blocks_Breaking_Activated(p, true);
                    sender.sendMessage("false");
                }
                else{
                    main.setRestoring_Blocks_Breaking_Activated(p, false);
                    sender.sendMessage("true");
                }
            }
          
            if (args.length==1 && args[0].equalsIgnoreCase("reset")){
                main.getConfig().set("locations", null);
                main.saveConfig();
            }
          
            if (args.length==1 && args[0].equalsIgnoreCase("tool")){
                ItemStack item = new ItemStack(Material.FEATHER, 1);
                ItemMeta im = item.getItemMeta();
                im.setDisplayName("Restoring Blocks' Editor");
                item.setItemMeta(im);
                ((HumanEntity) sender).getInventory().addItem(item);

            if (!(args[0]).equalsIgnoreCase("break") || !(args[0]).equalsIgnoreCase("place") || !(args[0]).equalsIgnoreCase("reset") || !(args[0]).equalsIgnoreCase("tool")){
                sender.sendMessage("[RestoringBlocks] Type \"rb\" for help");
            }
          
          
          
     return true;
    }
