    // 1. build an object with nested structure
    JsonObject jsonObject = Json.createObjectBuilder().add("firstName", "John").add("lastName", "Smith").add("age", 25).add("address", Json.createObjectBuilder().add("streetAddress", "21 2nd Street").add("city", "New York").add("state", "NY").add("postalCode", "10021")).add("phoneNumber", Json.createArrayBuilder().add(Json.createObjectBuilder().add("type", "home").add("number", "212 555-1234")).add(Json.createObjectBuilder().add("type", "fax").add("number", "646 555-4567"))).build();
    // 2. write the object to a string
    StringWriter stringWriter = new StringWriter();
    try (JsonWriter writer = Json.createWriter(stringWriter)) {
        writer.write(jsonObject);
    }
    String toString = stringWriter.toString();
    // 3. read object from the string
    JsonObject fromString = null;
    try (JsonReader jsonReader = Json.createReader(new StringReader(toString))) {
        fromString = jsonReader.readObject();
    }
    // 4. sanity check :)
    if (!jsonObject.equals(fromString)) {
        throw new IllegalStateException("json object read from string does not equal the one built");
