We will illustrate the first two approaches. The first approach is more efficient and is used when a large amount of data is processed. The second technique is convenient but the data must not be too large. The third technique is useful when it is more convenient to use specific Java classes to process data. For example, if the JSON data represent an address then a specific Java address class cane be defined to hold and process the data.
There are several Java libraries that support JSON processing including:
- Flexjson (http://flexjson.sourceforge.net/)
- Genson (http://owlike.github.io/genson/)
- Google-Gson (https://github.com/google/gson)
- Jackson library (https://github.com/FasterXML/jackson)
- JSON-io (https://github.com/jdereg/json-io ...
