可以在優化嗎?
package com.imooc.animal; public class Book { private String bookTitle; private String Author; private String publisher; private double price; public Book(String bookTitle, String author, String publisher, double price) { this.setbookTitle(bookTitle); this.setAuthor(author); this.setPublisher(publisher); this.setPrice(price); } public void setbookTitle(String bookTitle) { this.bookTitle = bookTitle; } public String getbookTitle() { return "書名:" + bookTitle; } public String getAuthor() { return "作者" + Author; } public void setAuthor(String author) { Author = author; } public String getPublisher() { return "出版社" + publisher; } public void setPublisher(String publisher) { this.publisher = publisher; } public double getPrice() { return price; } public void setPrice(double price) { if (price < 10) { System.out.println("圖書價格最低10元"); price=10; this.price =price; }else { this.price = price; } } public void Print() { String st =this.getbookTitle()+"\n"+this.getAuthor()+ "\n"+this.getPublisher()+"\n價格:"+this.getPrice(); System.out.println(st); } }
第二類
package com.imooc.animal; public class BookTest { public static void main(String[] args) { Book bo = new Book("紅樓夢", "曹雪", "人民出版", 11); Book bo1 = new Book("小李飛刀", "古龍", "中國出版", 55.5); bo.Print(); System.out.println("====================="); bo1.Print(); } }
