如何用Java生成一本书？急用！谢谢！
public class UserBook {
private String bookName;
private String author;
private String publishing;
public String toString() {
return "书名：" + bookName + " 作者：" + author + " 出版社：" + publishing;
}
public String getBookName() {
return bookName;
}
public void setBookName(String bn) {
this.bookName = bn;
}
public String getAuthor() {
return author;
}
public void setAuthor(String au) {
this.author = au;
}
public String getPublishing() {
return publishing;
}
public void setPublishing(String pub) {
this.publishing = pub;
}
public static void main(String[] args) {
UserBook ub = new UserBook();
System.out.println(ub);
}
}
用Java编写一个图书类程序：1.属性：图书编号，图书名称，出版社，库存量。2.构造方法：至少两个
package com.hua.excep;
public class Libary {
private int id;
private String name;
private String shop;
private int num;
//两个构造方法
//无参
public Libary() {
}
//四个参数
public Libary(int id, String name, String shop, int num) {
this.id = id;
this.name = name;
this.shop = shop;
this.num = num;
}
//输入图书信息
public void inputBook(int id,String name,String shop){
this.id=id;
this.name=name;
this.shop=shop;
}
//输出三个图书信息
public int getId() {
return id;
}
public String getName() {
return name;
}
public String getShop() {
return shop;
}
//修改库存
public void setNum(int num) {
this.num = num;
}
}
java创建一个图书类
public class Book {
public String name; //书名
public String author; //作者
public String publisher; //出版社
public String state; //状态：STATE_IN 在馆 STATE_OUT 外借
public static String STATE_IN = "in";
public static String STATE_OUT = "out";
public Book(String name, String author, String publisher){
this.name = name;
this.author = author;
this.publisher = publisher;
}
public Book(String name, String author, String publisher, String state){
this.name = name;
this.author = author;
this.publisher = publisher;
this.state = state;
}
public static void main(String[] args) {
Book book1 = new Book("西游记", "吴承恩", "新华出版社");
book1.setState(STATE_IN);
Book book2 = new Book("水浒传", "施耐庵", "新华出版社", STATE_IN);
}
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 String getPublisher() {
return publisher;
}
public void setPublisher(String publisher) {
this.publisher = publisher;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
}
java设计一个图书借阅程序
package Management;
import java.util.List;
import java.util.ArrayList;
public class Management {
public static ListBook bookList=null;
public Management() {
// TODO Auto-generated constructor stub
bookList=new ArrayListBook(100);

j++;
}
}
return book;
}
public Book[] ShowAllBook()

for(int i=0;ibookList.size();i++)
{
book[i]=bookList.get(i);
bookList.get(i).printInfo();
}
return book;
}
}
class Book

liabry.addbook(book);
System.out.println("还书成功");
}
}
java做一个简单的图书管理系统，大一新生，用基础做，软件能调试就行
从零开始学Java，本来利用数组只在一个界面就可以实现增删改查功能，学到接口后觉得实现分离效果会更好一些！所以进行了尝试，将管理员和用户中的图书查询，登录，图书出库合并在一起写了一个接口，用户类和管理员类实现这个接口！图书类写了一个抽象类里面都是一些图书的属性，用户类管理员类对图书类进行操作。
具体实现如下：
接口：存在三种方法 用户类和管理员类去实现这个接口，并实现着里面的方法
[java] view plain copy
public interface Person {
public boolean login(String user,String pwd); //登录方法
public void search(); //查询方法
public void reduce(String s,int i); // 图书出库
}
用户类： 实现接口，里面都是用户的方法，在测试类里调用这些方法实现其功能
[java] view plain copy
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class User implements Person{
private final String user = "user";
private final String pwd = "user";
List list = new ArrayList();
public void addBook(Book book){ //增加图书
list.add(book);
}
public boolean login(String user, String pwd) { //登录方法
if(this.user.equals(user) this.pwd.equals(pwd)){
return true;
}
return false;
}
@Override
public void reduce(String s, int i) { //结账
Iterator it = list.iterator();
while(it.hasNext()){
Book b = (Book)it.next();
if(b.getNum().equals(s)){
if(b.getCount() = i){
int m = b.getCount()-i;
b.setCount(m);
System.out.println("你的图书总价为："+(b.getPrice()*i));
}else
System.out.println("你输入的书本数目超出了当前库存！");
}else{
System.out.println("没找到,你要加入的图书！");
}
}
}
@Override
public void search() { //查询图书当前情况
Iterator it = list.iterator();
while(it.hasNext()){
Book b = (Book)it.next();
System.out.println(b.getNum()+"\t"+b.getName()+"\t"
+b.getAnthor()+"\t"+b.getFromTime()
+"\t"+b.getPrice()+"\t"+b.getCount());
}
}
}

package com.pv1;
import java.util.*;
public class Admin implements Person {

}
}
public void reduce(String num, int i) { // 图书出库
for (int j = 0; j list.size(); j++) {

图书类：抽象类，里面全部是属性，方便用户管理员对其操作。
[java] view plain copy

private String num ;
private String name;
private String anthor;
private String fromTime;
private double price;
private int count;
public String getNum() {
return num;
}
public void setNum(String num) {
this.num = num;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAnthor() {
return anthor;
}
public void setAnthor(String anthor) {
this.anthor = anthor;
}
public String getFromTime() {
return fromTime;
}
public void setFromTime(String fromTime) {
this.fromTime = fromTime;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
}
测试类：
[java] view plain copy
package com.pv1;
import java.util.*;
public class BookTest {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
Book bo = new Book(); //在开始时加入一本图书，所用对象
Book bo1 = null; //循环加入图书建立的对象，开始设成空，防止加入图书时被覆盖
List list = new ArrayList(); //建立一个集合，存储管理员要添加的图书信息的对象
Admin ad = new Admin(); //建立管理员对象，管理员操作时调用管理员类中对象
User us = new User(); //建立用户对象，管理员操作时调用用户类中对象
boolean ad1 = true; //接受进入管理员操作界面的返回值
boolean us1 = true; //接受进入用户操作界面的返回值
bo.setAnthor("刘冰"); //书籍为空，加入一本图书
bo.setCount(20);
bo.setNum("1001");
bo.setName("一本道");
bo.setFromTime("2015-2-50");
bo.setPrice(250.0);
ad.addBook(bo); //通过对象传递在管理员类中加入一本图书
us.addBook(bo);
System.out.print("请输入用户名："); //用户输入 用户名 密码
String user = input.next();
System.out.print("请输入密码：");//
String pwd = input.next();
ad1 = ad.login(user, pwd); //将 用户名 密码 传入管理员类中进行判断返回Boolean类型接受
us1 = us.login(user, pwd); //将 用户名 密码 传入用户类中进行判断返回Boolean类型接受
if (ad1) { //如果管理员类返回true进入 管理员操作界面
System.out.println("图书编号\t" + "书名\t" + "作者\t" + "出版日期\t" + "\t价格\t"
+ "库存");
ad.search();
while (true) {
bo1 = new Book();
System.out.println("1.查询 2.图书入库 3.图书出库 "
+ "4.新增图书 5.修改 6.删除 7.退出\t请输入您的选择：");
int xuan = input.nextInt();
switch (xuan) {
case 1:
System.out.println("图书编号\t" + "书名\t" + "作者\t" + "出版日期\t"
+ "价格\t" + "库存");
ad.search();
break;
case 2:
System.out.print("请输入你想入库的图书编号：");
String num = input.next();
System.out.print("请输入你想添加本图书的数量：");
int cou = input.nextInt();
ad.increase(num, cou);
break;
case 3:
System.out.print("请输入你想取出的图书编号：");
