java - JSONArray constructor issue

{"balance":1000.21,"is_vip":true,"num":100,"name":"foo"}

This is my json string. I want to iterate each element and get my output as

1000
true
100
foo

I tried creating JSONArray with the following syntax

  JSONArray jsonarr = new JSONArray(myString);

But the error thrown is

 "The constructor JSONArray(String) is undefined"

So what can be the possible solution this?

You have to use JSONObject class instead:

JSONObject jso = new JSONObject(yourJsonString);

// values
for(int i = 0; i<jso.names().length(); i++){
    System.out.println( jso.get( jso.names().getString(i) ) );
}
