About JSON : JSON(JavaScript Object Notation) is containing object and array.Key and Value pair that is separated with a colon(:) in JSON Object like {"Key" : "Value"}. The jsonTuples library parses JSON text to immutable JSON values, which can then be converted to List or Map for CRUD operations, and then back to JSON values. Raw JsonUtils.java import java.util.ArrayList; import java.util.Arrays; import java.util.List; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; import org.springframework.stereotype.Service; public class JsonUtils { In order to use Jakcson for comparing JSON objects, we add the following dependency in our POM.xml file: <dependency> <groupId>com.fasterxml.jackson.core</groupId> JavaTpoint offers too many high quality services. Such compare is validated automatically as soon as we write or paste our JSON objects on both sides. I require to fail when values are different. By assuming the JSON texts to be syntax correct, the Parser would work in lenient mode by default to get a bit higher throughput and neglect any errors that bring no ambiguities, as the unit test below: Notice there are many illegal XXXs would be neglected when people can still "guess" out the intended content. Defines limited JSON classes to enable JSON string processing as outlined in, Parses big JSON text block and saves the contents as, The JSON values can be used as media to compare Java Objects to get their minimum differences as another JSON Object. but I don't recommend using it since I ran into hard solved edge cases and lost interest.

How to make it only for keys ? An array is an ordered sequence of zero or more values. I've done good experience with JSONAssert. ThejsonTuples can parse given JSON texts to any of the seven typesIJSONValues in the above table. Many times, we need to compare two JSON objects to find whether both are the same or different from each other. The above test illustrates howJSONObject can be referred to as a Map whileJSONArray can refer its elements as aList.
