当我调用此方法时，它在 java 中不起作用

Question

当我从 class 公司调用方法 "getName(companyName)" 时，它不会从 yml 向用户发送公司名称，它只是抛出很多异常。但是，当我将方法 "getName(companyName)" returns 的代码放入 sender.sendMessage 时，它确实会向用户发送公司名称。这是为什么？

Class 方法执行位置：

package me.ben.Corporation.commands;

import me.ben.Corporation.Company;
import me.ben.Corporation.Config;
import me.ben.Corporation.Corporation;

import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;

public class CorporationCommand implements CommandExecutor
{
    Config companiesFile = Corporation.plugin.companiesFile;
    Company company;

    public boolean onCommand(CommandSender sender, Command cmd, String     cmdLabel, String[] args)
    {
        companiesFile.reload();

        if (cmdLabel.equalsIgnoreCase("corporation"))
        {
            if (args[0].equalsIgnoreCase("test"))
            {
                sender.sendMessage(company.getName(args[1]));
            }
        }
        return false;
    }
}

Class 其中方法 "getName(companyName)" 是：

package me.ben.Corporation;

public class Company
{
    Config companiesFile = Corporation.plugin.companiesFile;

    public String getName(String companyName)
    {
        companiesFile.reload();
        return companiesFile.getConfig().getString("companies." + companyName.toLowerCase() + ".name");
    }
}

插件读写的YAML文件：

    companies:
      simpleco:
        assets:
          cash: {}
          property: {}
        directors: {}
        expenses: {}
        liabilities: {}
        name: SimpleCo
        revenue: {}

让你的 getName() 方法 static.
