java——如何比较两组对象不使用 Comparator 和 Streams 覆盖 equals/hashCode

我有两个Set它是这样的：

Set s1 = createBooks();
Set s2 = createBooks(); // or any set of values

这种方法：

private Set createBooks() {

    List name = Arrays.asList("book 1", "book 2", "book 3");
    List type = Arrays.asList(BookType.TYPEONE, BookType.TYPETWO);

    Set listOfBooks = new HashSet<>();

    for(int i=0; i<2; i++) {
        Book book = new Book();
        book.setName(name.get(i));
        book.setType(type.get(i));
        listOfBooks.add(books);
    }

    return listOfBooks;
}

还有这门课：

Class Book {

 private String name;
 private BookType type;

 //here is getter and setter ...

 }

我确实做到了Comparator，但我不确定它是否正常工作：

   Comparator comparingBooks = (o1, o2) -> {
        if (o1.getName().compareTo(o2.getName()) == 0) {
            return o1.getType().compareTo(o2.getType());
        }
        return o1.getName().compareTo(o2.getName());
    };


     //I did try this implementation but am not sure it's working as well:

     //Comparator comparingBooks = Comparator.comparing((Book b)->b.getNName())
              .thenComparing(b->b.getType());

当预期结果为true:

s1 = (new Book("book 1", BookType.ONE), new Book("book 2", BookType.TWO));
s2 = (new Book("book 1", BookType.ONE), new Book("book 2", BookType.TWO));

当预期结果为false:

s1 = (new Book("book 1", BookType.ONE), new Book("book 2", BookType.TWO));     
s2 = (new Book("book 1", BookType.ONE), new Book("book 2", BookType.ONE));

我需要将这些集合与以下内容进行比较：

// this flag should validate any difference of Name 
// and Type by returning true, 
// if both Sets have exactly the same objects, 
// it should return false.
boolean compareBooks = s1.stream().anyMatch(a -> s2.stream().anyMatch(b -> comparingBooks.compare(a, b) != 0));

我也尝试过，但没有成功，总是返回相同的值：

    boolean compareBooks = SetUtils.isEqualSet(s1, s2);

我没有equals和hashcode实现，无法实现。

java 8和comparator还有其他方法来检查和比较这些集合吗？
