Java substring: 'string index out of range'

Question

I\'m guessing I\'m getting this error because the string is trying to substring a null value. But wouldn\'t the \".length() > 0\" part eliminate

Answer 1

I would recommend apache commons lang. A one-liner takes care of the problem.

pstmt2.setString(3, StringUtils.defaultIfEmpty(
    StringUtils.subString(itemdescription,0, 38), "_"));
