如何用Java解决这个问题

设计一个简单的Book类，数据成员是书名和编号，定义成员方法，该方法的功能是输出书名和编号，分别创建两个书的对象（具体书名和编号自己定义即可），并输出对象的信息。

public class ch02 {
    static class Book{
        private final String name;
        private final String numb;

        public Book(String name, String numb) {
            this.name = name;
            this.numb = numb;
        }

        public void print(){
            System.out.println("书名:"+name+",编号："+numb);
        }
    }
    
    public static void main(String[] args) {
        Book b=new Book("白雪公主","123456");
        b.print();

        Book b1=new Book("海洋王国","023456");
        b1.print();
    }
}

public class Book {

    private String bookName;
    private String bookId;


   public Book(String bookName, String bookId) {
        this.bookName = bookName;
        this.bookId = bookId;
    }

    public String getBookName() {
        return bookName;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }

    public String getBookId() {
        return bookId;
    }

    public void setBookId(String bookId) {
        this.bookId = bookId;
    }

    @Override
    public String toString() {
        return "Book{" +
                "bookName='" + bookName + '\'' +
                ", bookId='" + bookId + '\'' +
                '}';
    }
}

```
