是不是一般通过构造方法传参时，用不到get方法，那public，private属性没有区别？

测试：

Book one=new Book("红楼梦","曹雪芹","人民文学出版社",10.0);

类：

public Book(String bookName, String authorName, String publication, double price) {

this.bookName = bookName;

this.authorName = authorName;

this.setPublic(publication);

this.setPrice(price);

}
