Easily Read and Write JSON like XML.This project provides Java developers with a path query-like approach, allowing them to easily extract data from complex JSON structures and locate target nodes without manual traversal.

String json = "...";
Object document = Configuration.defaultConfiguration().jsonProvider().parse(json);

String author0 = JsonPath.read(document, "$.store.book[0].author");
String author1 = JsonPath.read(document, "$.store.book[1].author");
