IT技术比喻

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import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;

import java.util.List;
import java.util.Scanner;
public class BookWork {
static ListBook data;
private static Scanner input;
public static void main(String[] args) {
if (!initBook("d:/book.txt")) {
System.out.println("初始图书列表失败 ..");
return;
}
input = new Scanner(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");
int number = Integer.parseInt(input.next());
if (number == 1) {
findBook();
} else if (number == 2) {
delBook();
} else if (number == 3) {
System.out.println("退出");
break;
} else {
System.out.println("这个不是图书查询java代码我要图书查询java代码的...重来...");
System.out.println();
}
} catch (Exception e) {
e.printStackTrace();
System.out.println("这个不是我要的...重来...");
System.out.println();
}
}
}
private static void delBook() {
System.out.println("请输入要删除的书名或编号：");
String key = input.next();
if (key != null!key.equals("")) {
for (Book book : 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");
}
private static void findBook() {

System.out.println("找到了 图书 " + book.toString());
return;
}
}
}
System.out.println("没有您要找的");
}
