请老师指点还有什么地方可以改进？

package book;

public class Book {

 //私有属性：书名、作者、出版社、价格

    private String name,author,publisher;

    private double price;

 //通过构造方法实现属性赋值

   public Book(String name,String author,String publisher,double price){

    this.name=name;

    this.author=author;

    this.setPublisher(publisher);

    this.setPrice(price);

   }

   public String getName(){

       return "书名："+name;

   }

   public String getAuthor(){

       return "作者："+author;

   }

    public void setPublisher(String publisher){

       this.publisher=publisher;

   }

   public String getPublisher(){

       return "出版社："+publisher;

   }

   public void setPrice(double price){

       if(price<=10){

           System.out.println("你输入了无效价格，自动将价格调至10");

           this.price=10;

       }else this.price=price;

   }

   public String getPrice(){

       return "价格:"+price+"元";

   }

   /*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

   */

 //信息介绍方法，描述图书所有信息

}

对象：

package book;

public class BookTest {

public static void main(String[] args) {

Book one =new Book("红楼梦","曹雪芹","人民文学出版社",5);

System.out.println(one.getName());

System.out.println(one.getAuthor());

System.out.println(one.getPublisher());

System.out.println(one.getPrice());

System.out.println("==============================");

Book two =new Book("小李飞刀","古龙","中国长安出版社",55.5);

System.out.println(two.getName());

System.out.println(two.getAuthor());

System.out.println(two.getPublisher());

System.out.println(two.getPrice());

}

}
