如果a
Member有子项，则可以正确地将子项添加到拼合列表中，但是会错过其
Member本身。只需将成员的
else添加移动到块添加之外，就可以了：
private static List<Member> convertToFlatList(List<Member> memberList, List<Member> flatList){ for (Member member : memberList) { // Always add the member to flatList flatList.add(memeber); // If it has children, add them toore if (member.getChildren() != null) { convertToFlatList(member.getChildren(), flatList); } } return flatList;}
