Converting string array to hashmap

Question

I have the following response

T2269|175@@2a1d2d89aa96ddd6|45464047

By using the split("\\|") i have converted into string array object. The meaning for the each field is as follows:

T2269                  id
175@@2a1d2d89aa96ddd6  cid
45464047               refno

No i have to convert it into HashMap object . Is their any solution for the above..

The above response is given for example. In real, the length of the string array object is 36.

What would be the keys and the values in your map? Do you mean a map with three entries (id = T2269, cid = 175..., refno = 4546...) ? Or a map where the values are objects with three fields (id, cid, refno)? In that case what would be the key? — assylias, Jul 05 '12 at 08:29

You have to loop and add the results one by one. Declare an array with the keys, something like:

static String[] keys = new String[]{"id", "cid", "refno", ...};

and then

String[] s = text.split("\\|");
for (int i = 0; i < s.length; i++)
  map.put(keys[i], s[i]);

final String[] fields = input.split("\\|");
final Map<String, String> m = new HashMap<String, String>();
int i = 0;
for (String key : new String[] {"id", "cid", "refno"})
  m.put(key, fields[i++]);

The key should be unique, so obviously using the ID as a key would make perfect sense, and the value you can store as an array/list containing the id,cid,refno, or you can create an object containing thos fields and store it.
