I am trying to save the groups in a string to an array so that I can use them in individual variables if I need to. For this I use split but for some reason I only get the full string in the first position in the array: ultimate_array[0]. If I want to use ultimate_array[1] I get an exception like "out of bounds". Do you have any idea what am I doing wrong?
String string_final = "";
String[] ultimate_array = new String[100];
String sNrFact = "";
string_final="Nrfact#$idfact1#$valfact1#$idfact2#$valfact2#$idfact3#$valfact3#$idfact4#$valfact4#$idfact5#$valfact5#$idfact6#$valfact6#$idfact7#$valfact7#$idfact8#$valfact8#$idfact9#$valfact9#$idfact10#$valfact10";
ultimate_array = string_final.split("#$");
sNrFact = ultimate_array[0];

The SPLIT function belongs to VBA. It isn't part of Excel because it returns an array. Spreadsheets show elements of arrays in different cells. Therefore the result of the SPLIT function can't be shown in a single cell which, Excel being unable to display the result, would render the function itself useless.
backslash-dot is invalid because Java doesn't need to escape the dot. You've got to escape the escape character to get it as far as the regex which is used to split the string.
The split() function works by scanning the given string or line based on the separator passed as the parameter to the split() function. In case the separator is not passed as a parameter to the split() function, the white spaces in the given string or line are considered as the separator by the split() function.
The split takes an regular expression and $ is a special character (end of string) so you have to escape it with backslash \. Anyway it is also special character, this time in Java, so you have to escape it also. The final code is:
ultimate_array = string_final.split("#\\$");
You need to escape $ (end of string)
ultimate_array = string_final.split("#\\$");
