I was quite amazed by IntelliJ's refactoring capabilities just few days back. I had code like below

  switch(sort) {
      case "asc":
        sortedComments = topicComments
                .stream().map(Comment::getThreadComments).filter(Objects::nonNull).flatMap(Collection::stream)
                .sorted(Comparator.comparingLong(PostResponse::getCommentPostedTimeMilles)).collect(Collectors.toList());
        break;
      case "desc":
        sortedComments = topicComments
                .stream().map(Comment::getThreadComments).filter(Objects::nonNull).flatMap(Collection::stream)
                .sorted(Comparator.comparingLong(PostResponse::getCommentPostedTimeMilles).reversed()).collect(Collectors.toList());
       break;
  }

I selected the first case and applied "Extract to method" and IntelliJ automatically suggested and applied the method to the second case also. Not sure if Eclipse will do that.
