The service returns json in the following format :
[
"ABC",
"HELLO",
"GOODBYE"
]
How can I count the number of strings inside the json?

That is an array. Just use array.length to find out the number of elements. – grim_i_am Aug 28 '17 at 22:34

Is it a json array then? – worrynerd Aug 28 '17 at 22:39

you need a json parser. It will tell you how many elements are in a json array. There are few on the net, i.e. http://www.oracle.com/technetwork/articles/java/json-1973242.html – Serge Aug 28 '17 at 22:40

if it' unmarshaled from JSON ( String) to the object array it will be possible to call `.length` – Chol Nhial Aug 28 '17 at 22:40

You can use a Json parser like GSON, to deserialize the JSON.
// Deserialization
int[] ints2 = gson.fromJson("[1,2,3,4,5]", int[].class);
// ==> ints2 will be same as ints
System.out.println(int2.length);
see https://github.com/google/gson/blob/master/UserGuide.md#TOC-Array-Examples

`String[] myList = gson.fromJson("[\"one\", \"two\", \"three\"]", String[].class)` I believe that would be how to deserialize a list of strings – Chol Nhial Aug 28 '17 at 22:46
