Enhanced 'for' statement

Reports enhanced for statements.

Example:

  for (int x: Arrays.asList(1, 2, 3)) {
    System.out.println(x);
  }

After the quick-fix is applied:

  for (Iterator<Integer> iterator = Arrays.asList(1, 2, 3).iterator(); iterator.hasNext(); ) {
    final int x = iterator.next();
    System.out.println(x);
  }
