开发一个表示图书的Book类
package com.base;
public class Book {
private int bookNumber; //编号
private String bookName; //书名
private String author; //作者
private double price; //价格
private String publication; //出版社
private String date; //出版日期
public int getBookNumber() {
return bookNumber;
}
public void setBookNumber(int bookNumber) {
this.bookNumber = bookNumber;
}
public String getBookName() {
return bookName;
}
public void setBookName(String bookName) {
this.bookName = bookName;
}
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 String getPublication() {
return publication;
}
public void setPublication(String publication) {
this.publication = publication;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String show() {
return "编号:"+bookNumber+",书名:"+bookName+",作者:"+author+",价格:"+price+",出版社:"+publication+",出版日期:"+date;
}
//修改价格
public void updatePrice (double price) {
this.price=this.price+price;
}
}
