1.自己做的
package BOOk; public class Book { private String name; private String author; private double price; private int store; private String publishDate; public Book(String name, String author, double price, int store, String publishDate) { this.name = name; this.author = author; this.price = price; this.store = store; this.publishDate = publishDate; } public Book() { super(); // TODO Auto-generated constructor stub } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAuthor() { return author; } public void setAuthor(String author) { this.author = author; } public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } public int getStore() { return store; } public void setStore(int store) { this.store = store; } public String getPublishDate() { return publishDate; } public void setPublishDate(String publishDate) { this.publishDate = publishDate; } public void add(){ } }

總結:1.注意程式碼框架的搭建
2.注意新增圖書的呼叫
3.學習呼叫各種方法
