Java Reference
In-Depth Information
value pairs, which can be represented either as a
java.util.Map
or
as the properties of a
April 1, 2014, might be represented as:
{
"year"
"year"
:
2014
,
"month"
"month"
:
4
,
"day"
"day"
:
1
}
JSON Arrays are ordered lists, represented in Java either as arrays or as
java.util.List
s.
A list of two dates might look like this:
{
[{
"year"
"year"
:
2014
,
"month"
"month"
:
4
,
"day"
"day"
:
1
}
,
{
"year"
"year"
:
2014
,
"month"
"month"
:
5
,
"day"
"day"
:
15
}
]
}
JSON is free-format, so the preceding could also be written, with some loss of human-read-
ability but no loss of information or functionality, as:
{
[{
"year"
"year"
:
2014
,
"month"
"month"
:
4
,
"day"
"day"
:
1
}
,
{
"year"
"year"
:
2014
,
"month"
"month"
:
5
,
"day"
"day"
:
15
}
]}
Hundreds of parsers have, I'm sure, been written for JSON. A few that come to mind in the
Java world include the following:
stringtree.org
Very small and light weight
json.org parser
Widely used because it's free and has a good domain name
