Looking for corresponding values

Here is one example where you want to know how many values are equal to '1' in 28 different tags.

int res = 0;
for(int i = 1; i <= 28; i++)
{
  if ("1".equals(_doJava.get("_str"+i)))
    res++;
}

return res;

Moving sum

An other exemple to make a moving sum, by taking the values each 10min moving:

double somme = 0;
_doJava.get("_str1", -1440);
for (int i =0; i<1440; i+=10){
    if(!_doJava.get("_str1", -i)!.equals(""))
       {
        somme += Str.ToDouble(_doJava.get("_str1", -i));
    }
}
return somme;
