arrays - How to parse json into android to compare users location to nearest 10 locations? -

im getting server response store locations , master array dictionaries:

[ masterarray : {name = main, lat = 15.948 long= 88.853 }, {name = 5th street, lat = 15.294 long= 88.743 }, {name = cannes blvd, lat = 15.235 long= 88.765 }, ]

i need loop through each store, lat/long, compare users location, create new array top 5 nearest locations.

ive got far:

try { //get master array of locations jsonarray jsonarray = new jsonarray(arrays.aslist(contentasstring));

            //loop through each dictionary in array              (int = 0; < jsonarray.length; i++) {                  //get lat&long                 jsonobject sys  = jsonarray.getjsonobject("master");                 name = sys.getstring("name");                 latitude = sys.getstring("lat");                 longitude = sys.getstring("long");                  //create location object                  //send location.distanceto() method                  //create new array distance field added original values              }              //sort , nearest 5 locations              //create cards top 5 locations               //better use mirror api         } catch (exception e) {             // todo auto-generated catch block             e.printstacktrace();         } 

what im stuck in creating location object , how hook distanceto method empty:

//get distances     public float distanceto (location dest) {          //compare distance passed user location          //return distance float         return 1;     } 

any appreciated.
