java图书借阅源代码 java图书借阅管理系统全部源代码
JAVA对图书馆借阅书籍情况编程
首先这个问题涉及到三个对象和一个动作，即图书对象，学生对象和借书信息的对象，和完成“借书”的动作，图书对象又可以包含图书编号，书名，作者，出版社，出版日期等等，学生对象包含学生编号，姓名，性别，班级，系别等等。借书信息对象包含图书编号，学生编号，借书时间，借书数目等等

写好这三个类，然后分别new一个图书和学生的对象实例，
接着写一个借书动作过程的方法，将图书对象和学生对象的属性保存到借书信息的对象中....代码略
利用Java实现图书的借阅管理功能，采用文本文件方式存储数据自行设计数据结构。
//只实现了图书的添加
package com.suncheng.main;

java设计一个图书借阅程序

for(int i=0;ibookList.size();i++)
{
if(bookName.equals(bookList.get(i).getName()))
{
book[j]=bookList.get(i);
j++;
}
}
return book;

public Book[] ShowAllBook()

for(int i=0;ibookList.size();i++)
{

bookList.get(i).printInfo();
}
return book;
}
}
class Book

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAuthor() {

}
public void setAuthor(String author) {
this.author = author;
}
void printInfo()
{
System.out.println("书名为"+this.name+"作者为"+this.author);
}
}
class Reader
{
private String name;
public void borrowbook(Book book) {
Management liabry=new Management();
for(int i=0;iliabry.bookList.size();i++)

System.out.println("借书成功！");
break;
}
}
}
public void backbook(Book book) {

liabry.addbook(book);
System.out.println("还书成功");
}
}
用java编写一个 图书馆图书借阅管理系统
---------------------------------------------------
给你修改了三个地方：
1.borrowBooks方法中，将System.out.println("你要借吗？"); 改为：
System.out.println("你要借吗？输入1表示借，其他数字表示不借。");
保证输入的时候输入的数字，否则会报出异常。
2.borrowBooks方法中，将self[score] = all[9]; 改为：self[score] = all[i];
如果是all[9]，那么就始终是最后一本书籍信息了。
3.have方法中，你是想将所借的书籍信息都打印出来。修改的比较多，下面注释代码是原来的。
void have(Books[] self) {
// for (int i = 0; i 2; i++) {
// self[i].showBookInfo();
// }
for (int i = 0; i 3; i++) {
if(self[i]!=null)
self[i].showBookInfo();
}
}
