Rest Assured verifying JSON list of key/value pairs

Using Rest Assured (io.restassured) in Java and have the following JSON response format

{
"products": [
    {
      "name": "toy1",
      "price": 99
    },
    {
      "name": "toy2",
      "price": 88
    },
    {
      "name": "toy3",
      "price": 99
    }
  ]
}

I'm trying to find if a specific product exist given it's name and price.

So the following result (or assert) is expected

I tried:

• converting the JSON into a list of maps, but the overall solution was really messy
• found a package that would be convenient and solve my problem, but there's restrictions preventing me from using it
• considered flattening it, but that won't work since there would be key clashes

There are 2 solutions

1. Create a POJO class for the sample JSON (leverage online json to pojo converters - https://json2csharp.com/code-converters/json-to-pojo)
2. If you don't want to create extra POJO class, you can go ahead with io.restassured.path.json.JsonPath.

Here's an example of 2nd one.

public static void main(String[] args) {
    // Example JSON response
    String jsonResponse = "{ \"products\": ["
            + "{ \"name\": \"toy1\", \"price\": 99 },"
            + "{ \"name\": \"toy2\", \"price\": 88 },"
            + "{ \"name\": \"toy3\", \"price\": 99 }"
            + "] }";

    // Parse JSON response
    JsonPath jsonPath = new JsonPath(jsonResponse);

    // Check for product existence
    System.out.println(doesProductExist("toy1", 99, jsonPath)); // true
    System.out.println(doesProductExist("toy2", 99, jsonPath)); // false
    System.out.println(doesProductExist("toy2", 88, jsonPath)); // true
    System.out.println(doesProductExist("sometoy", 99, jsonPath)); // false
}

public static boolean doesProductExist(String name, int price, JsonPath jsonPath) {
    List<Map<String, Object>> products = jsonPath.getList("products");
    return products.stream()
        .anyMatch(product -> name.equals(product.get("name")) && price == (int) product.get("price"));
}
