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();
}
}

java做一个简单的图书管理系统，大一新生，用基础做，软件能调试就行
从零开始学Java，本来利用数组只在一个界面就可以实现增删改查功能，学到接口后觉得实现分离效果会更好一些！所以进行了尝试，将管理员和用户中的图书查询，登录，图书出库合并在一起写了一个接口，用户类和管理员类实现这个接口！图书类写了一个抽象类里面都是一些图书的属性，用户类管理员类对图书类进行操作。
具体实现如下：
接口：存在三种方法 用户类和管理员类去实现这个接口，并实现着里面的方法
[java] view plain copy
public interface Person {
public boolean login(String user,String pwd); //登录方法
public void search(); //查询方法
public void reduce(String s,int i); // 图书出库
}
用户类： 实现接口，里面都是用户的方法，在测试类里调用这些方法实现其功能
[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){ //增加图书
list.add(book);
}
public boolean login(String user, String pwd) { //登录方法
if(this.user.equals(user) this.pwd.equals(pwd)){
return true;
}
return false;
}
@Override
public void reduce(String s, int i) { //结账
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("你的图书总价为："+(b.getPrice()*i));
}else
System.out.println("你输入的书本数目超出了当前库存！");
}else{
System.out.println("没找到,你要加入的图书！");
}
}
}
@Override
public void search() { //查询图书当前情况
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());
}
}
}
