java - ArrayList ignore null value causing ArrayIndexOutOfBoundsException -

i trying specific data line using ! split. example:

s!arc!256!547291!840.50!9038.00!840.50!9038.00!519.50!9038.00!321.00!0.00!counterclockwise!assembly_top!bat-2-cr1632-t0_r!bt2k! 

so when split line using ! , put in array, array should contain 16 data. facing problem when data like

s!line!257!37825 1!3525.00!10720.00!4525.00!10720.00!6.00!!!!!assembly_top!csco-label-asy-73-sn-comb_r!!  

and ignore last data null or "". when try take data[15] , problem arrayindexoutofboundsexception keep pop out.below code write:

string[] data = $line_list.get(k).split("!");                      if ($line_list.get(k).startswith("s!") &&  $line_list.get(k).contains("assembly_top"))                     {                               $graphic.append(data[15])                                 .append("!")                                 .append(data[14])                                 .append("!")                                 .append("top")                                 .append("\n");                     } 

any way solve problem??

split eliminates trailing empty strings. therefore, in example length of array 15, data[15] out of bounds.

0 "s" 1 "line" 2 "257" 3 "37825 1" 4 "3525.00" 5 "10720.00" 6 "4525.00" 7 "10720.00" 8 "6.00" 9 "" 10 "" 11 "" 12 "" 13 "assembly_top" 14 "csco-label-asy-73-sn-comb_r" 

you must check data.length > 15 before accessing data[15].

here's relevant quote javadoc of split :

this method works if invoking two-argument split method given expression , limit argument of zero. trailing empty strings therefore not included in resulting array.
