Java 小型图书馆管理系统

Java 小型图书馆管理系统

以下为小型图书馆管理系统模式图：

模式总体概述：

其中IBorrower接口确定Borrower类标准，Library类为单例设计模式，即图书馆只有一个。Book类为Borrower类的内部类，libraryBook类为Library类的内部类。最后利用PlatForm类进一步的封装。对于类方法中的核心，主要是数组的“增删查改”操作，本项目中三次运用了这些操作，分别在Borrower、Library、PlatForm类方法中。

`IBorrower接口：`

// package com.wu.demo;/**
*  @date  2020-10-30 10:08:48
*  @author  一夜星尘
*  @version  1.8.0*/// 图书借阅人标准
public interface IBorrower {public abstract void borrowBook(String bookName,String bookAuthor,float bookPrice,Library libary);public abstract void returnBook(String bookName,String bookAuthor,float bookPrice,Library libary);
}

`Borrower类：`

// package com.wu.demo;/**

*  @version  1.8.0*/
public class Borrower implements IBorrower{protected String borrowerName;protected long borrowerNumber;private int booksNumber;private static final int MAX_NUMBER_OF_BOOKS  = 4; //最大借书容量private Book[] books = new Book[MAX_NUMBER_OF_BOOKS];public Borrower(String borrowerName,long borrowerNumber) {this.borrowerName = borrowerName;this.borrowerNumber = borrowerNumber;this.booksNumber = 0;}private class Book{private String bookName;private String bookAuthor;private float bookPrice;public Book(String bookName,String bookAuthor,float bookPrice){Book.this.bookName = bookName;Book.this.bookAuthor  = bookAuthor;Book.this.bookPrice = bookPrice;}public String getName() {return Book.this.bookName;}public String getAuthor() {return Book.this.bookAuthor;}public float getPrice() {return Book.this.bookPrice;}}@Override/*** 借书操作*/public void borrowBook(String bookName,String bookAuthor,float bookPrice,Library library) {if(booksNumber>=MAX_NUMBER_OF_BOOKS) {System.out.println("超过最大借书容量");return;}books[booksNumber++] = new Book(bookName,bookAuthor,bookPrice);// 移除图书馆书籍,更新图书馆信息library.removeBook( bookName,bookAuthor, bookPrice);}@Override/*** 还书操作*/public void returnBook(String bookName,String bookAuthor,float bookPrice,Library library) {// 前提是有书的情况下if(booksNumber<=0) {return;}int index = -1;for(int i = 0 ; i < books.length ; i++) {if(books[i].bookName.equals(bookName) && books[i].bookAuthor.equals(bookAuthor) && books[i].bookPrice == bookPrice) {index = i;break;}}if(index < 0) {System.out.println("你并没有该书籍");return;}for(int i = 0; i < booksNumber-1 ; i++) {if(i>=index) {books[i] = books[i+1];}}booksNumber --;// 还入图书馆,更新图书馆信息library.addBook(bookName,bookAuthor,bookPrice);}/*** 借书人信息*/public void borrowerInfo() {int i = 0;System.out.println("------------------------------借阅人信息------------------------------");System.out.println("借阅人姓名："+this.borrowerName);System.out.println("借阅人学号："+this.borrowerNumber);for(;i < booksNumber ; i++) {System.out.println("第"+(i+1)+"本书: ");System.out.println("书籍名称："+books[i].getName());System.out.println("书籍作者："+books[i].getAuthor());System.out.println("书籍价格："+books[i].getPrice());}System.out.println("当前借阅书本数为: "+booksNumber+"  剩余容量为: "+(MAX_NUMBER_OF_BOOKS-i));System.out.println("------------------------------------------------------------------------");}}
