Explicit array filling

Reports loops that can be replaced with Arrays.setAll() or Arrays.fill() calls.

This inspection suggests replacing loops with Arrays.setAll() if the language level of the project or module is 8 or higher. Replacing loops with Arrays.fill() is possible with any language level.

Example:

  for (int i=0; i<array.length; i++) {
     array[i] = calc(i);
  }

After the quick-fix is applied:

Arrays.setAll(array, this::calc);
