Conversion between JSON strings and java objects [json-lib] And jsonjson-lib During development, data is often exchanged with other systems. The data exchange formats include XML and JSON. JSON, as a lightweight data format, is mo

These features make JSON an ideal data exchange language.JSON is constructed in two structures:A collection of name/value pairs (A collection of name/value pairs). In different languages, it is understood as objects (object), record (record), structure (struct), Dictionary (dictionary), hash table (hash table), keyed list (keyed list), or associative arra

Fortunately, XPath2.0 is a powerful retrieval engine integrating functions, predicates, and axes. without Java code writing any traversal logic, you can add any logic in the form of a natural language in the XPath request. for example, you can directly send the request "How many books were published by David West in 2004?" You can get the
