java - Text to nested JSON -

we have output pig stored in text file. tuples containing user path in form of urls.

here 2 sample tuples:

    (http://www.flipkart.com/",http://www.flipkart.com/jewellery",http://www.flipkart.com/jewellery/rings",http://www.flipkart.com/jewellery/rings/agni"):1 (http://www.flipkart.com/",http://www.flipkart.com/jewellery",http://www.flipkart.com/jewellery/rings",http://www.flipkart.com/jewellery/rings/nakshatra"):1 

we want our output in form of nested json:

{"id":0,       "name":"(http:\/\/www.flipkart.com\/\"", "data":"", "children": {"id":1, "name":"http:\/\/www.flipkart.com\/jewellery\"", "data":"", "children":     {"id":2,     "name":"http:\/\/www.flipkart.com\/jewellery\/rings\"",     "data":"","children":         [{"id":3,         "name":"http:\/\/www.flipkart.com\/jewellery\/rings\/agni\"):1",         "data":"",         "children":"[]"         },         {"id":4,         "name":"http:\/\/www.flipkart.com\/jewellery\/rings\/nakshatra\"):1",         "data":"",         "children":"[]"         }]     } } } 

how can in java?

there not shortcut - need clean string , make json. guess trying make jstree?

if want in javascript - write regex, run loop add other variables , convert json.stringify method convert json object. or in case of java clean string, make pojo , create json object using gson or other library.
