Error when working with the substring

Question

Hi,
i am getting a error when using a substring
Scenario : from Flat file to IDoc
input = 30 char
output1 = first 10 chars
output2 = last  4 chars
when my input filed has the maximum number of characters say 30 in this case, then my scenerio works fine.
but if my input string has only first 6 chars, remaining all "spaces" . i get a stringindexoutof boundexception, when i post a flat file. Can anyone tell me if we are suppose to handle such conditions differently

Hi,
you could do it like:
> if input.length >= 10 char
> output1 = first 10 chars
> else output1 = input
> if input.length >= 4 chars
> output2 = last 4 chars
> else output2 = input
