先考虑软件环境问题，确定好开发工具和数据库。图书馆管理系统，我的理解就是一个档案管理而已，数据库用sql
---------------------------------------------------
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。
voidhave(Books[]self){
//for(inti=0;i2;i++){
//self[i].showBookInfo();
//}
for(inti=0;i3;i++){
if(self[i]!=null)
self[i].showBookInfo();

最近好多人要这份源码啊感觉..有建表脚本..使用mysql数据库..建表之后就可以直接运行了.
