Jackson in Java: Role & Uses

In Java, Jackson is a library used for JSON processing, primarily for converting Java objects to JSON data and vice versa. It provides a set of tools and APIs for serialization (converting Java objects to JSON strings) and deserialization (converting JSON strings to Java objects). Jackson supports various data types including primitive data types, collections, arrays, custom objects, and can handle a variety of complex data structures flexibly. Widely used in Java projects, Jackson can simplify the development process and improve the readability and maintainability of code.
