RestAssured returns array instead of String

Question

I have this test I'm writing in RestAssured. I want to extract the id in String but always returning it as array. This is the test I have written so far.

@Test(priority = 1)
    public static void searchForUsername( ) throws Throwable {
        ValidatableResponse response= given().contentType(ContentType.JSON).queryParam("username",
                "Delphine").log().parameters().get("https://jsonplaceholder.typicode.com/users").then().log().all();

        JsonPath extractor = response.extract().jsonPath();
        userId = extractor.getString("id");
        System.out.println(userId);
    }

It prints it as [9] instead of 9

Reason: the object that you extract is in an array. So when you extract, the id will be in an array.

Solution: From list of id, you can get by index.

@Test
void name2() {
    Response res = RestAssured.given()
            .queryParam("username", "Delphine")
            .get("https://jsonplaceholder.typicode.com/users");
    int id = (Integer) res.jsonPath().getList("id").get(0);
    System.out.println(id);
}
