Well, actually that figure is a Jsonobject. A Object Array would be something like:

Object[] arr = new Object[];
List<Object> list = new ArrayList<Object>;
/* etc */

Back to the subject, you can capture the keys. This catch will return you a Iterator.

With that Iterator you can go through all the keys and thus capture the values through a while or do..while

JSONObject j = new JSONObject("{\"number1\":\"value1\", \"number2\":\"value2\", \"number3\":\"value3\"} ");
Iterator<String> keys = j.keys();

// Verifica se há mais alguma key
while (keys.hasNext() {
    // Captura a key e seu valor; e avança para a próxima
    System.out.println( j.get( keys.next() ).toString() );
}

Or you can use the for

JSONObject j = new JSONObject("{\"number1\":\"value1\", \"number2\":\"value2\", \"number3\":\"value3\"} ");

for ( Iterator<String> Keys = j.keys(); Keys.hasNext(); ) {
    System.out.println( j.get( Keys.next() ).toString() );
}
