JAVA對圖書館借閱書籍情況編程

首先這個問題涉及到三個對象和一個動作，即圖書對象，學(xué)生對象和借書信息的對象，和完成“借書”的動作，圖書對象又可以包含圖書編號，書名，作者，出版社，出版日期等等，學(xué)生對象包含學(xué)生編號，姓名，性別，班級，系別等等。借書信息對象包含圖書編號，學(xué)生編號，借書時間，借書數(shù)目等等

寫好這三個類，然后分別new一個圖書和學(xué)生的對象實例，

接著寫一個借書動作過程的方法，將圖書對象和學(xué)生對象的屬性保存到借書信息的對象中....代碼略

利用Java實現(xiàn)圖書的借閱管理功能，采用文本文件方式存儲數(shù)據(jù)自行設(shè)計數(shù)據(jù)結(jié)構(gòu)。

用java編寫一個 圖書館圖書借閱管理系統(tǒng)

---------------------------------------------------

給你修改了三個地方：

1.borrowBooks方法中，將System.out.println("你要借嗎？"); 改為：

System.out.println("你要借嗎？輸入1表示借，其他數(shù)字表示不借。");

保證輸入的時候輸入的數(shù)字，否則會報出異常。

2.borrowBooks方法中，將self[score] = all[9]; 改為：self[score] = all[i];

如果是all[9]，那么就始終是最后一本書籍信息了。

3.have方法中，你是想將所借的書籍信息都打印出來。修改的比較多，下面注釋代碼是原來的。

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();

}

}
