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();

}

}
