I succeeded that convert to JsonArray from String of JsonArray format. And I try to convert that JsonObject from JsonObject in JsonArray. Could you explain about this method?

No you cannot convert jsonarray to jsonobject as contents with in {} are jsonobject and [] and these are jsonarray you need to change the structure. the things are key and value pairs like {key : value } in jsonobject and and [val, val, val] in json array.

You are confusing me with your tags: "java" and "jquery", did you mean "JavaScript"? Because Java has no relation with jQuery....

If you mean JavaScript, this may be your solution:

var jsonArrayStr = "[{test1:'test',test2:2,test3:'test3'},{test1:'test',test2:2,test3:'test3'}, {test1:'test',test2:2,test3:'test3'}]";
var jsonArray = JSON.parse( jsonArrayStr );

If you mean really Java, try the following code:

JSONArray jsonArray = new JSONArray(jsonArrayStr);

Dependencies:

import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
