How to return the more than two map objects in Java

Question

Actually I am trying to parse the two api's json data in the same class. I know it should not be done but this is the requirement. I am getting data from the hashmap. And I want to add it in the table.But the problem is program adds only last item in table. but while debugging it's giving all values.

Here is my code:

public class services2
{
    public Map<Object, Object> getReportees(String idOfEmp) throws  Exception {
        ......
        if(resp.getStatus() != 200){
            System.err.println("Unable to connect to the server");
        }
        String output = resp.getEntity(String.class);
        //Store the JSON objects in an array
        //Get the index of the JSON object and print the values as per the index
        JSONParser parse = new JSONParser();
        JSONObject jobj = (JSONObject)parse.parse(output);
        JSONArray jsonarr_1 = (JSONArray) jobj.get("list");
        Map<Object, Object> map=new HashMap<Object,Object>();
        for(int i=0;i<jsonarr_1.size();i++){
            JSONObject jsonobj_1 = (JSONObject)jsonarr_1.get(i);
            JSONObject jive      = (JSONObject)jsonobj_1.get("jive");
            String var   = jive.get("username").toString();
            values = var;
            if(resp1.getStatus() != 200){
                system.err.println("Unable to connect to the server");
            }
            String output1 = resp1.getEntity(String.class);
            JSONObject jobjs = (JSONObject) new JSONParser().parse(output1);

            JSONArray jsonarr_11 = (JSONArray) jobjs.get("issues");
            System.out.println("count"+jsonarr_11.size());
            Object obj3 = jsonarr_11.size();
            int counter = (Integer) obj3;
            System.out.println(counter);

            Object obj1 = jsonobj_1.get("displayName");
            Object obj2 = jive.get("username");

            map.put(obj1, obj2);
            map.put("obj3", obj3);
            System.out.println(obj3);
        }
        return  map;  //for the map obj3 return only the last count that is 1
    }
}

Here when I am trying to send the map obj3. I am getting only the last value. I actually want the count in a correct way.

                    This is the output:
             Number  id     username       count
               1    A12345  Anagha R        1
               2    M12345  Madhusudan S    1
               3    AT12345 Amreen Taj      1
                   Expected output is:
               1    A12345  Anagha R        0
               2    M12345  Madhusudan S    0
               3    AT12345 Amreen Taj      1

When I am trying to print in the console it is giving me the right count but when I am trying through the map it is sending only the last value that is count 1.

Actually here the problem is not returning more than two map objects rather the last value is only being passed from the map object. — RAMYA, Jan 17 '19 at 06:00

The problem is in below line of code:

map.put("obj3", obj3);

Each time you are replacing the value for "Obj3" instead of incrementing the existing value of the map.

Instead what you need to do is:

if(map.containsKey("obj3")
{
    Object obj3 = map.get("obj3");
    //put your logic of incrementing or adding the count 
    //Lets say it is new Value
    map.put("obj3",newValue)
}

Actually I am not fetching any key nor value from the second api rather I am just taking the arraysize which will give me the count.Then how can I implement it?? – RAMYA Jan 17 '19 at 06:32

You can try using a list of a map like the following:

List<HashMap<Object,Object>>
