1-7编程有没有标准答案来参考一下啊，理解下大家的构思

public class Book {
      //私有属性：书名、作者、出版社、价格
        private String bookName;
        private String author;
        private String pubName;
        private double price;
      //通过构造方法实现属性赋值
        public Book(double price,String bookName,String author,String pubName){
            this.price = setPrice(price);
            this.bookName = setBookName(bookName);
            this.author = author;
            this.pubName = pubName;
             
        }
        /*通过公有的get/set方法实现属性的访问，其中：
        1、限定图书价格必须大于10，如果无效需进行提示，并强制赋值为10
        2、限定作者、书名均为只读属性
        */
        public String setBookName(String bookName){
            return this.bookName =bookName;
        }
        public String getBookName(){
            return this.bookName;

        }
        public double setPrice(double price){
            if(price<10.0){
                System.out.println("图书最低价格10元");
                this.price = 10;
            }else{

    }
