How to get Map values and create String type for each of them

Question

I have a Map<String, String> values which returns me key-pair values, I want each values as a string.

For example output should be like :

String a = "map value 1"
String b = "map value 2"

How do I make it, should I use iterator, if yes then how can I get each values in String?

Output :

11-30 14:05:03.344 21403-21403/com.example D/getActionValue: Map Values are : {com.ibm.mce.sdk.NOTIF_SOURCE_ID=-1638692152, com.ibm.mce.sdk.NOTIF_SOURCE_PAYLOAD={"attribution":"Campaign Name Group"}, value={"hasLoyaltyId":"please enter name"}, com.ibm.mce.sdk.NOTIF_SOURCE={"subject":"Title","message":"Notification Message","notification-action":{"name":"go to screen","value":{"hasLoyaltyId":"please enter name"},"type":"gotoscreen"}}}

After 1st level Iteration, i am still not getting values, coz it contains multiple values within which you can see in output

11-30 16:19:36.998 9429-9429/com.teleca.sam.engine D/getActionValue: Attribution is : Campaign Name 30
11-30 16:19:36.998 9429-9429/com.teleca.sam.engine D/getActionValue: Map Values are : {com.ibm.mce.sdk.NOTIF_SOURCE_ID=1671068670, com.ibm.mce.sdk.NOTIF_SOURCE_PAYLOAD={"attribution":"Campaign Name 30"}, value={"hasLoyaltyId":"please enter name "}, com.ibm.mce.sdk.NOTIF_SOURCE={"subject":"Title 1","message":"Notification Message 1","notification-action":{"name":"go to screen","value":{"hasLoyaltyId":"please enter name "},"type":"gotoscreen"}}}
11-30 16:19:36.999 9429-9429/com.example D/getActionValue: key : com.ibm.mce.sdk.NOTIF_SOURCE_ID
11-30 16:19:36.999 9429-9429/com.example D/getActionValue: value : + value
11-30 16:19:36.999 9429-9429/com.example D/getActionValue: key : com.ibm.mce.sdk.NOTIF_SOURCE_PAYLOAD
11-30 16:19:36.999 9429-9429/com.example D/getActionValue: value : + value
11-30 16:19:36.999 9429-9429/com.example D/getActionValue: key : value
11-30 16:19:36.999 9429-9429/com.example D/getActionValue: value : + value
11-30 16:19:36.999 9429-9429/com.example D/getActionValue: key : com.ibm.mce.sdk.NOTIF_SOURCE
11-30 16:19:36.999 9429-9429/com.example D/getActionValue: value : + value

Yes you can as follow,

for (Map.Entry<String, Object> e : hashmap.entrySet()) {
        String key = e.getKey();
        Object value = e.getValue();
        String a=e.getKey()+" "+e.getValue();
        Log.e("Map",a);
    }

I got that, I made changes, I have another worry here. The value also contains multiple values within, which I again need to iterate?? Let me put output in question

yes, you need to iterate again as follows JSONObject menu = jObject.getJSONObject(e.getKey()); Map<String,String> map = new HashMap<String,String>(); Iterator iter = menu.keys(); while(iter.hasNext()){ String key = (String)iter.next(); String value = menu.getString(key); map.put(key,value); }

You could just iterate through the Map. The documentation for entrySet states:

Returns a Set view of the mappings contained in this map.

So based on that, you can use it in your iterator to do what you want.

Iterator it = values.entrySet().iterator();
while (it.hasNext()) 
{
    Map.Entry pair = (Map.Entry)it.next();
    System.out.println(pair.getKey() + " = " + pair.getValue());
}
