java - Take values from ArrayList<HashMap<String, String>> -


i have problem getting value arraylist<hashmap<string, string>>.

my code is:

arraylist<hashmap<string, string>> myarraylist;

and then:

hashmap<string, string> map = new hashmap<string, string>(); map.put(tag_id, id); map.put(tag_name, name); myarraylist.add(map);

if want name, example, tried follow obtain runtime error (the application crashes):

system.out.println(myarraylist.get(1).get(tag_name));

thank much!

system.out.println(myarraylist.get(1).get(tag_name));

arraylist 0-based. get(0) instead.
