设计一个library类，它包含一个内部类Book,Book类有书名,作者和出版年份的属性.library类应该有一个方法打印所有书籍的信息

设计一个名为`Library`的类，它包含一个内部类`Book`作为它的组成部分。`Book`类将拥有三个私有属性：`title`(书名)、`author`(作者)和`yearOfPublication`(出版年份)。为了提供访问和操作这些信息的功能，我们需要在`Book`类中定义getter和setter方法，以及一个代表书籍内容的构造函数。

public class Library {
    // 内部类Book
    private class Book {
        private String title;
        private String author;
        private int yearOfPublication;

        public Book(String title, String author, int year) {
            this.title = title;
            this.author = author;
            this.yearOfPublication = year;
        }

        // getter和setter方法
        public String getTitle() {
            return title;
        }

        public void setTitle(String title) {
            this.title = title;
        }

        public String getAuthor() {
            return author;
        }

        public void setAuthor(String author) {
            this.author = author;
        }

        public int getYearOfPublication() {
            return yearOfPublication;
        }

        public void setYearOfPublication(int yearOfPublication) {
            this.yearOfPublication = yearOfPublication;
        }
    }

    // Library类的方法来管理图书
    public void printBooks(Book[] books) {
        for (Book book : books) {
            System.out.println("书名: " + book.getTitle());
            System.out.println("作者: " + book.getAuthor());
            System.out.println("出版年份: " + book.getYearOfPublication());
            System.out.println("--------------------");
        }
    }
}

// 使用示例
public static void main(String[] args) {
    Library library = new Library();
    Book book1 = library.new Book("Java编程思想", "Bruce Eckel", 2004);
    Book book2 = library.new Book("深入浅出Python", "Mark Lutz", 2015);

    Book[] books = {book1, book2};
    library.printBooks(books);
}
