Loop can be replaced with 'List.replaceAll()'

Reports loops which can be collapsed into a single List.replaceAll() call.

Example:

for (int i = 0; i < strings.size(); i++) {
  String str = strings.get(i).toLowerCase();
  strings.set(i, str);
}

After the quick-fix is applied:

strings.replaceAll(String::toLowerCase);

This inspection only reports if the language level of the project or module is 8 or higher.
