Its developers extol the combination of fast, correct, lightweight, and ergonomic attributes of the library.[1][2] ImplementationJackson provides many ways of working including simple POJO converted to/from JSON for simple cases. Jackson provides a set of annotations for mapping too.[3][1] Usage exampleSample code for reading and writing with POJOs may look like the following:[1] public class ReadWriteJackson { public static void main(String[] args) throws IOException { ObjectMapper mapper = new ObjectMapper(); String jsonInput = "{\\"id\\":0,\\"firstName\\":\\"Robin\\",\\"lastName\\":\\"Wilson\\"}"; Person q = mapper.readValue(jsonInput, Person.class); System.out.println("Read and parsed Person from JSON: " + q); Person p = new Person("Roger", "Rabbit"); System.out.print("Person object " + p + " as JSON = "); mapper.writeValue(System.out, p); }} References1. ^1 2 {{Cite web|url= http://wiki.fasterxml.com/JacksonHome |title= History |date= |accessdate= 12 February 2016 |website= FasterXML |publisher= FasterXML |last= |first= |deadurl=yes |archiveurl=https://web.archive.org/web/20160211195332/http://wiki.fasterxml.com/JacksonHome |archivedate= 11 February 2016 |df= }} 2. ^{{Cite book |title = The Jackson Cookbook |last = Young |first = T.M. |publisher = Learnpub |year = 2013 |location = |volume = |pages = }} 3. ^{{Cite book|title = Java Cookbook|last = Darwin|first = I.F.|edition = 3rd|publisher = O'Reilly|year = 2014|location = Sebastopol, USA|volume = |pages = 656-657}} External links
