Java JSON Tutorial - JSON Syntax

JSON syntax can be summarized as follows:

• Data is represented in name/value pairs.
• Curly braces hold objects, the name/value pairs are separated by ,.
• Square brackets hold arrays and values are separated by ,.

JSON supports the following two data structures:

Data structure	Description
Collection of name/value pairs	key:value,key:value,
Ordered list of values	[1,2,3,4]

Example

The following JSON data specifies books.

{
    "book": [
    {
       "id":"01",
       "language": "Java",
       "edition": "third",
       "author": "java2s.com"
    },
    {
       "id":"02",
       "language": "JSON",
       "edition": "second"
       "author": "java2s.com"
    }]
}
