In this section, we will show you h ow to  convert XML to JSON using Jackson. Note Extensible Markup Language (XML) lets you define and store data in a shareable manner. XML supports information exchange between computer systems such as websites, databases, and third-party applications. Predefined rules make it easy to transmit data as XML files over any network because the recipient can use those rules to read the data accurately and efficiently. Note JSON  (JavaScript Object Notation) is a lightweight format that is used for data interchanging. JSON  is built on two structures:  A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.  An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. Download Jackson < dependency > < groupId >com.fasterxml.jackson.core</ groupId > < artifactId >jackson-databind<

Hello everyone, Here we will show how to convert JSON array String to List The Jackson library is composed of three components: Jackson Databind, Core, and Annotation. Jackson Databind has internal dependencies on Jackson Core and Annotation. Therefore, adding Jackson Databind to your Maven POM dependency /Gradle list will include the other dependencies as well.
