What is the error in the Minecraft plugin code?

Question

Java

In the game, instead of the message string, it displays null. It's near the end of the code.

package ru.zhigul.chat;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;

public class Commands implements CommandExecutor{
  
  private main plugin;
  protected String message;
  protected String arg;
  protected String name;
  public Commands(main plugin) {
    this.plugin = plugin;
  }

  @Override
  public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
       if(args.length == 0) {
         sender.sendMessage(ChatColor.RED + "Используй эту команду вот так: /try <action>");
         return false;
       }
       
       for(int i = 0; args.length == i; i=i+1)
       {	
         message = message + args[i] + " ";
       }
       	name = sender.getName().toString();
       	sender.sendMessage(ChatColor.DARK_PURPLE + "*" + name + " " + message); 
       	return true;
  }
}

Such a loop for(int i = 0; args.length == i; i=i+1)will never be executed, so the field messagewill not be initialized.
