我的txt文件如下所示：-
类型：战士
健康：100
级别：1
经验：0
最大生命值：100
药剂-小：2

- Medium : 1

     - Large : 0

我想用“：”字符后面的数字创建对象（英雄=新战士（生命值，等级，经验值，最大健康值，库存）我的代码根本不起作用。这是我的密码。当我打印arraylist时，它会打印出我需要的所有元素。但除了它不做任何事情，也没有显示任何错误消息。（谢谢）

private void loadHero() throws IOException {
        try {

            BufferedReader reader = new BufferedReader(new FileReader(file));
            ArrayList<String> listOfVariables = new ArrayList<>();
            String line;

           int count = 0;
           while((line= reader.readLine())!=null){
               String[] val = line.split(":");
               String members = val[1];
               listOfVariables.add(members);
               count+=1;
