㈡ 用java編寫一個 圖書館圖書借閱管理系統
---------------------------------------------------
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，其他數字表示不借。");
保證輸入的時候輸入的數字，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]，那麼就始終是最後一本書籍信息了。
3.have方法中，你是想將所借的書籍信息都列印出來。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();
}
}

㈣ 用java編寫一個，圖書管理系統
可以使用Baihi告訴我你的題目
有空能搞定你無法解決的題目
如果你有類似的要求也能聯系我
ES:\\
交易提醒:預付定金有風險
交易提醒:用戶名中包含聯系方式勿輕信
㈤ JAVA圖書管理系統會用到的技術
如果伺服器不用資料庫那麼會用到，鏈表，或者Hash表，如果有負載均衡，會用到socket，如果伺服器存儲空間小，那麼會用到壓縮技術，如果你還打算列印票據，那麼會用到嵌入式技術。
㈥ 用JAVA做一個圖書館管理系統,不需要用到資料庫
