Is JSON faster than XML?

JSON is faster because it is designed specifically for data interchange. JSON encoding is terse, which requires less bytes for transit. JSON parsers are less complex, which requires less processing time and memory overhead. XML is slower, because it is designed for a lot more than just data interchange.

Which is more secure XML or JSON?

XML is more secure as compared to JSON. JSON seems less secured as compared to XML. In parsing, the XML DOM (Document Object Model) allows access and editing of XML data. In the case of parsing, the eval method of JavaScript can parse JSON data.

Why XML is preferred over JSON?

Usually JSON is more compact, and faster to parse. Prefer XML if: You need to process the data on the client, and you can leverage XSL for that. Chances are the XML + XSL chain will work faster than JSON + JavaScript especially for big chunks of data.

How to read and write JSON using Jackson in Java?

Jackson reads and writes JSON through a high-performance Jackson Streaming API, with a low memory and process overhead.The only problem with Streaming API is that we need to take care of all the tokens while parsing JSON data.All the JSON values must be read/write in the same order in which it arrives.
