java图书管理系统

㈠ 求一个java图书管理系统代码，不需要图形化，命令行就可以，只要求实现导入图书，查询，删除

importjava.io.BufferedReader;
importjava.io.File;
importjava.io.FileReader;
importjava.util.ArrayList;
importjava.util.List;
importjava.util.Scanner;

publicclassBookWork{

if(!initBook("d:/book.txt")){
System.out.println("初始图书列表失败..");
return;
}
input=newScanner(System.in);
while(true){
try{
System.out.println("请输入操作：");
System.out.println("1.找书2.删除图书3.退出");
intnumber=Integer.parseInt(input.next());
if(number==1){
findBook();
}elseif(number==2){
delBook();
}elseif(number==3){
System.out.println("退出");
break;
}else{
System.out.println("这个不是我要的...重来...");
System.out.println();
}

}catch(Exceptione){
e.printStackTrace();

㈡ 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();
}
}

㈣ 用java编写一个，图书管理系统

可以使用Baihi告诉我你的题目
有空能搞定你无法解决的题目
如果你有类似的要求也能联系我

㈤ JAVA图书管理系统会用到的技术

如果服务器不用数据库那么会用到，链表，或者Hash表，如果有负载均衡，会用到socket，如果服务器存储空间小，那么会用到压缩技术，如果你还打算打印票据，那么会用到嵌入式技术。

㈥ 用JAVA做一个图书馆管理系统,不需要用到数据库

packagecom.efounder.formbuilder.dat;

importjava.util.Iterator;
importjava.util.Map;
importjava.util.Map.Entry;

importcom.efounder.formbuilder.fmt.FmtCol;

/**

㈦ Java使用面向对象编程思维编写图书管理系统:增加,查询,修改,删除,退出，怎么写

return;
