Question

        public void loadArenas(){

        File folder = new File(plugin.getDataFolder().getPath() + "/arenas/");
        for (final File fileEntry : folder.listFiles()) {
            if (fileEntry.isDirectory()) {
            } else {
                //String fileNameWithOutPre = FilenameUtils.getBaseName(fileEntry.toString());
                Arena arena = new Arena(folder.toString());
                System.out.println(Arena.arenaObjects);
            }
        }
    }

该代码获取文件列表，将它们添加到列表中，然后将其打印出来。但这是打印出来的：

[me.noraaron1.Tk.MultiArenas.Arena@3d2b2429]

但当我尝试使用此代码进行签名时：

@EventHandler
public void onSignChange(SignChangeEvent e) {
    if (e.getLines().length > 0 && !e.getLine(0).equalsIgnoreCase("[TheKiller]")) return;
    if(!e.getPlayer().hasPermission("tk.MakeSign")) return;
    if (e.getLines().length < 3) {
        e.getBlock().breakNaturally();
        e.getPlayer().sendMessage("A TK sign must have at least 3 lines.");
        return;
    }
    if(Arena.arenaObjects.contains(e.getLine(2))){

        e.setLine(0, ChatColor.BLUE + "[TheKiller]");
        e.setLine(3, ChatColor.BLUE + "0" + ChatColor.GREEN + "/" + ChatColor.DARK_GREEN + "20");
    }else{
        e.getBlock().breakNaturally();
        e.getPlayer().sendMessage("The arena name you provided is not valid!");
        return;

    }
}

它告诉我，竞技场名称不在列表中，即使它是。它永远不会改变。

当你在方法中使用object / class / whatever作为字符串时，它将使用toString方法来获取它需要用于该字符串的内容。要解决此问题，您有两种方法： 1.您可以覆盖类

中的toString（）方法

示例：

    @Override
    public String toString(){
        return this.variable + "," + this.othervariable;
    }

您可以自己手动执行转换

System.out.println(obj.variable + "," + obj.othervariable);

加载Arenas返回一个奇怪的字符串
