Violation |
1 | Unmatched statement reg.setPattern(from); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted |
2 | Unmatched statement messageDigest=MessageDigest.getInstance(algorithm); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted |
