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();

圖書館管理系統java怎麼做
先考慮軟體環境問題，確定好開發工具和資料庫。圖書館管理系統，我的理解就是一個檔案管理而已，資料庫用sql
server；然後最好設計一個資料庫模型和功能模型，把你的系統的主要功能和需要的資料庫表有一個雛形。你需要用戶登錄，則至少有一個用戶管理的功能，如果更複雜一點，應該有一個許可權管理，日誌管理。如果還要分角色，則需要角色管理。然後肯定得有一個圖書入庫，圖書借出，圖書歸還等等功能；然後就是詳細設計了，每個功能模塊大概需要哪些更詳細的功能點；做好前面幾部非常關鍵，不然後面才發現設計跟需求出現大的偏差，後果就非常嚴重了；後面就是代碼編寫測試，純技術問題，一般問題不大。
java做一個簡單的圖書管理系統，大一新生，用基礎做，軟體能調試就行
從零開始學Java，本來利用數組只在一個界面就可以實現增刪改查功能，學到介面後覺得實現分離效果會更好一些！所以進行了嘗試，將管理員和用戶中的圖書查詢，登錄，圖書出庫合併在一起寫了一個介面，用戶類和管理員類實現這個介面！圖書類寫了一個抽象類裡面都是一些圖書的屬性，用戶類管理員類對圖書類進行操作。
具體實現如下：
介面：存在三種方法 用戶類和管理員類去實現這個介面，並實現著裡面的方法
[java] view plain copy
public interface Person {
public boolean login(String user,String pwd); //登錄方法
public void search(); //查詢方法
public void reduce(String s,int i); // 圖書出庫
}
用戶類： 實現介面，裡面都是用戶的方法，在測試類里調用這些方法實現其功能
[java] view plain copy
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class User implements Person{
private final String user = “user”;
private final String pwd = “user”;
List list = new ArrayList();
public void addBook(Book book){ //增加圖書
list.add(book);
}
public boolean login(String user, String pwd) { //登錄方法
if(this.user.equals(user) this.pwd.equals(pwd)){
return true;
}
return false;
}
@Override
public void reduce(String s, int i) { //結賬
Iterator it = list.iterator();
while(it.hasNext()){
Book b = (Book)it.next();
if(b.getNum().equals(s)){
if(b.getCount() = i){
int m = b.getCount()-i;
b.setCount(m);
System.out.println(“你的圖書總價為：”+(b.getPrice()*i));
}else
System.out.println(“你輸入的書本數目超出了當前庫存！”);
}else{
System.out.println(“沒找到,你要加入的圖書！”);
}
}
}
@Override
public void search() { //查詢圖書當前情況
Iterator it = list.iterator();
while(it.hasNext()){
Book b = (Book)it.next();
System.out.println(b.getNum()+”\t”+b.getName()+”\t”
+b.getAnthor()+”\t”+b.getFromTime()
+”\t”+b.getPrice()+”\t”+b.getCount());
}
}
}
