java图书管理系统源码

3. 采用JAVA设计一个小型图书管理程序（只要增删查改）

使用java语言设计一款小型图书管理系统，能够通过主界面根据关键字查询图书信息，能够添加图书信息和删除过去图书信息

4. JAVA版的图书管理系统

送你一份代码，结构大致按照你的需求了，自己增加一些小功能，不会的话请教你同学。
分给我，钱就不用了。

5. 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{

staticList<Book>data;
privatestaticScannerinput;

publicstaticvoidmain(String[]args){
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();
System.out.println("这个不是我要的...重来...");
System.out.println();
}
}
}

privatestaticvoiddelBook(){
System.out.println("请输入要删除的书名或编号：");
Stringkey=input.next();
if(key!=null&&!key.equals("")){

for(Bookbook:data){
if(book.number.equals(key)||book.name.contains(key)){
data.remove(book);
System.out.println("图书"+book.toString()+"已删除");
return;
}
}
}
System.out.println("没有您要删除的");

}

privatestaticvoidfindBook(){
System.out.println("请输入要查找的书名或编号：");
Stringkey=input.next();

if(book.number.equals(key)||book.name.contains(key)){
System.out.println("找到了图书"+book.toString());
return;
}
}
}
System.out.println("没有您要找的");
}

privatestaticbooleaninitBook(Stringstring){
try{
System.out.println("图书导入中...");
System.out.println("列表文件--"+string);

Filefile=newFile(string);
if(!file.exists()){
returnfalse;
}
data=newArrayList<Book>();
BufferedReaderbufferedReader=newBufferedReader(newFileReader(file));
Stringline="";
while((line=bufferedReader.readLine())!=null){

}
}catch(Exceptione){

}
returntrue;
}

publicstaticclassBook{
Stringnumber;
Stringname;

publicBook(Stringnumber,Stringname){

}
}
