java - put method in the json object adds value to the first of the jsonobject; -


consider following piece of code:

jsonobject json = new jsonobject();   json.put("one", 1);   json.put("two", 2);   json.put("three", 3);

if print jsonobject prints this

{"three":"1","two":"2","one":"1"}

but want this.

{"one":"1","two":"2","three":"3"}

please help. in advance.

the documentation @ http://www.json.org/javadoc/org/json/jsonobject.html says:

a jsonobject unordered collection of name/value pairs.

in other words, properties of object accessed name, not position , default serialized form not guarantee specific order.

strict positioning comes arrays:

jsonarray json = new jsonarray();  json.put("1"); json.put("2"); json.put("3");  json.tostring(); // results in ["1", "2", "3"]

the easiest workaround solve problem use sortedkeys() method , iterating jsonobject key key, produce json string manually in ever order necessary. implementing custom comparator might also.
