thanks in advance !!

i thought problem possibly 2d structure of array, , suggested links 1d. here suggested solution 2d case build simple test on data.

import java.util.arraylist;  public class testapp {      public static void main(string[] args){          string[][] data =          {{"datos varios", "datos empresa", null},          {"listado2", "listado2 extendido", null},          {"pendientes validar", "pendientes liquidar", "liquidados"},         {"pendientes aprobar", "pendientes pago", "pagados"}};          string[][] cleaneddata = removenull(data);          system.out.println("before");         printarray(data);         system.out.println("after");         printarray( cleaneddata );     }      public static void printarray(string[][] arr2d){         for(string[] arr1d: arr2d){             for(string s: arr1d){                 system.out.print(s+", ");             }             system.out.print("\n");         }     }      public static string[][] removenull( string[][] arr2d) {         //         arraylist<arraylist<string>> list2d = new arraylist<arraylist<string>>();         //         for(string[] arr1d: arr2d){             arraylist<string> list1d = new arraylist<string>();             for(string s: arr1d){                 if(s != null && s.length() > 0) {                     list1d.add(s);                 }             }             // possibly not want empty arrays in 2d array             // removed them             if(list1d.size()>0){                 list2d.add(list1d);             }         }         string[][] cleanarr = new string[list2d.size()][];         int next = 0;         for(arraylist<string> list1d: list2d){             cleanarr[next++] = list1d.toarray(new string[list1d.size()]);         }         return cleanarr;     } }
