thanks in advance!

you use gson purpose... following code might you

import com.google.gson.gson;  public final class jsonvalidation {  private static final gson gson = new gson();   public static boolean isvalidjson(string json) {    try {       gson.fromjson(json, object.class);       return true;   } catch(com.google.gson.jsonsyntaxexception ex) {        return false;   }   }  }

you here more info... https://github.com/google/gson/blob/master/userguide.md

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
