This can lead to complications when trying to assert or manipulate the data as per your requirements. In this post, we will explore how to remove the root property from a Java POJO API response, specifically focusing on a common case involving nested JSON objects. The Problem: Unwanted Root Property in API Response Imagine you receive a JSON response from an API that looks like this: [[See Video to Reveal this Text or Code Snippet]] You have converted this JSON into Java POJO classes but you are having difficulty extracting just the data array without the unwanted root property. This root property is currently presenting issues when performing data assertions. The Solution: Extracting the data List To effectively eliminate the root property from your response and isolate the data you need, you can directly convert the data list from your response. Below are the steps to achieve this within your Java code. Step 1: Define Your POJO Classes You already have defined your POJO classes; here’s a brief outline: Datum Class: Represents the individual data points with properties like id, name, year, color, and pantone_value. [[See Video to Reveal this Text or Code Snippet]] Root Class: Contains the overall structure of the response including the properties you want to ignore.

Conclusion Removing the root property from a Java POJO API response is straightforward with the right methods in place. By focusing on converting only the necessary data list, you can ensure that your assertions and data manipulations run smoothly. If you face similar issues in your Java projects, remember to isolate the relevant data directly from your POJO structures. Happy coding!
