how to add value into List<Map<String, Object>>?
提问by Rohan Kishibe
I'm trying to add a value to an ArrayList.
我正在尝试为ArrayList.
Here is the code I wrote:
这是我写的代码：
List<Map<String, Object>> list = new ArrayList<>();
list.put(1,"foo", (Object)"bar");
But, this does not work. Anybody have an idea?
但是，这不起作用。有人有想法吗？
采纳答案by shure
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
Map<String, Object> map = new HashMap<String, Object>();
map.put("foo", "bar");
list.add(map);
