ArrayList IndexOutOfBoundException JSP -

-

i taking 12 records database , storing in resultset since cannot fetch each element resultset whereever want. using arraylist store resultset data , using arraylist.get() method retrieve each element.

but problem data coming database can less 12 records have accessed arraylist.get(12) throws indexoutofboundexception. want check whether array.get(12)th element out of bound or not before printing value of it.

i have tried if(arraylist.get(12)!=null) doesn't work because again trying access 12th record not exist in arraylist.

if list contains 12 items , want last one, have use .get(11), since lists, arrays, sets, etc., 0-based indexed in java. on other hand, if want first one, have use .get(0) instead of .get(1) (which returns second one).

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.
