In this article we will show how to use this Jackson API for creating JSON. import org.json.simple.JSONObject; Create a new object for JSONObject, using the put () method of the jsonObject the add they key and value pairs into it. Let's analyze this JSON. a client-side scripting language to enrich web user-interfaces and create dynamic web pages (e.g., form input validation, and immediate response to user's actions). It also provides unmodifiable map view to the JSON object name/value mappings. To convert a JSON object into a Java object, you'll use the readValue () method of the ObjectMapper instance, which deserializes it into the provided class reference: JavaScript Object Notation (JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. Let's say your JSON is: { "status":"OK . This is an object that has title (string), lecture (string), examDate (date), studentNumber (numeric value, int is the best option for this case.)
