我在 Java 的 Hashmap 中有一个键值对，我正在按以下方式遍历 Map。
ArrayList<String> mysection = new ArrayList<String>();
ArrayList<String> temp = new ArrayList<String>();
Iterator it = Map.entrySet().iterator();
while (it.hasNext()){
Map.Entry pairs = (Map.Entry)it.next();
System.out.println(" = " + pairs.getValue());
mysection.add(pairs.getKey().toString());
temp.add(pairs.getValue().toString());
it.remove(); // avoids a ConcurrentModificationException
}
这似乎很好，但循环运行一次并创建一长串与键关联的值。我不想那样。我希望每个值都存储在 ArrayList 中，但不是这样发生的。所有值都存储在第一个索引本身中。
其次，即使我尝试分叉，我也找不到合适的方法。首先我想通过“，”运算符拆分字符串，但字符串本身包含几个“，”
请建议我应该针对第一个问题具体做什么，我不希望将所有值作为单个字符串。
谢谢
