Question

I have some json like [{"person":"123abc"}] in variable JSON_STRING i try parse json to string like this

    JSONObject person = (new JSONObject(JSON_STRING));
    String name = person.getString("person");
    String test= "123abc";
    if(name == test){
       System.out.print("Success");
    }else{

Here:

if(name == test){

You compare references not values. Use :

if(name.equals(test)){

actually, he does compare the string(s). I think you mean: "You compare references, not values" – Stultuske Dec 27 '17 at 11:19

if(name == test){ should be if(name.equals(test)){

==is used to compare references, and equals is using to compare values
