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

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();

}

}
