4实现方式
主要有如下几个类：
Book.java
书类：
package homeWork05;
public class Book {
private int bookId;
private String bookName;
private String bookAuthor;
private String publicDatae;
private double bookPrice;
private int bookNomber;
public int getBookId() {
return bookId;
}
public void setBookId(int bookId) {
this.bookId = bookId;
}
public String getBookName() {
return bookName;
}
public void setBookName(String bookName) {
this.bookName = bookName;
}
public String getBookAuthor() {
return bookAuthor;
}
public void setBookAuthor(String bookAuthor) {
this.bookAuthor = bookAuthor;
}
public String getPublicDatae() {
return publicDatae;
}
public void setPublicDatae(String publicDatae) {
this.publicDatae = publicDatae;
}
public double getBookPrice() {
return bookPrice;
}
public void setBookPrice(double bookPrice) {
this.bookPrice = bookPrice;
}
public int getBookNomber() {
return bookNomber;
}
public void setBookNomber(int bookNomber) {
this.bookNomber = bookNomber;
}
}
BookBiz.java:
书操作类：
package homeWork05;
import java.util.Arrays;
public class BookBiz {
public void CreateTable(Book[] books) {
System.out.println("书号\t书名\t作者\t发布时间\t\t价格\t库存");
for (int i = 0; i < books.length; i++) {
System.out.println(books[i].getBookId() + "\t" + books[i].getBookName() + "\t" + books[i].getBookAuthor()
+"\t" + books[i].getPublicDatae() + "\t" + books[i].getBookPrice() + "\t"
+books[i].getBookNomber());
}
}
public boolean BuyBook(int id, int no, Book[] books) {
boolean is = false;
for (int i = 0; i < books.length; i++) {
if (books[i].getBookId() == id) {
System.out.println(books[i].getBookName() + ":" + books[i].getBookPrice());
System.out.println("数量:" + no);
System.out.println("小计：" + books[i].getBookPrice() * no);
if (books[i].getBookNomber() - no >= 0) {
books[i].setBookNomber(books[i].getBookNomber() - no);
is = true;
}
}
}
return is;
}
public boolean ChangeBooks(Book b, Book[] books, boolean add) {
boolean is = false;
if (add) {
for (int i = 0; i < books.length; i++) {
if (books[i].getBookId() == b.getBookId()) {
books[i].setBookNomber(books[i].getBookNomber() + b.getBookNomber());
is = true;
}
}
}else {
for (int i = 0; i < books.length; i++) {
if (books[i].getBookId() == b.getBookId()) {
if (books[i].getBookNomber() - b.getBookNomber() >= 0) {
books[i].setBookNomber(books[i].getBookNomber() - b.getBookNomber());
is = true;
}
}
}
}
return is;
}
public Book[] AddBooks(Book b, Book[] books) {
books = Arrays.copyOf(books, books.length + 1);
books[books.length - 1] = b;
return books;
}
}
BookTube.Java:
书吧类：

BookTubeTest：
书吧测试类：
package homeWork05;
public class BookTubeTest {
public static void main(String[] args) {
BookTube bt = new BookTube();
InitUser(bt.getUsers());
InitBook(bt.getBooks());
new BookTubeBiz(bt);
}
public static void InitUser(User[] users) {
for (int i = 0; i < users.length; i++) {
users[i] = new User();
users[i].setUserName("user" + (i + 1));
users[i].setPassWord("user" + (i + 1));
boolean isAdmin;
if (i % 2 == 0) {
isAdmin = true;
} else {
isAdmin = false;
}
users[i].setAdmin(isAdmin);
}
}
public static void InitBook(Book[] books) {
for (int i = 0; i < books.length; i++) {
books[i] = new Book();
books[i].setBookId(10001 + i);
books[i].setBookName("book" + (i + 1));
books[i].setBookAuthor("TY");
books[i].setPublicDatae("2017-8-26");
books[i].setBookPrice(22.58);
books[i].setBookNomber(5);
}
}
}
User：
用户类：
packagehomeWork05;
public class User {
private String userName;
private String passWord;
private boolean isAdmin;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
public boolean getAdmin() {
return isAdmin;
}
public void setAdmin(boolean isAdmin) {
this.isAdmin = isAdmin;
}
}
UserBiz：
用户操作类：
packagehomeWork05;
public class UserBiz {
public void Login(User u) {
System.out.println("******欢迎光临图书系统******");
if (u.getAdmin()) {
System.out.println("欢迎管理员" + u.getUserName() + "!");
} else {
System.out.println("欢迎用户" + u.getUserName() + "!");
}
}
public User getUser(String un, String pw, User[] users) {
User u = new User();
u.setUserName(null);
for (int i = 0; i < users.length; i++) {
if (users[i].getUserName().equals(un) && users[i].getPassWord().equals(pw)) {
u = users[i];
break;
}
}
return u;
}
}
通过以上几个类的协同工作就构成了我们这个简单的图书管理系统了！而且简单易使用。
