复制这段内容后打开百度网盘手机App，操作更方便哦

 代码核心思路---将用户名信息，书籍信息以对象的形式存至容器<list>内。

我的Java文件都在book包内。

1.先创建  用户类

package book;

public class Personinformation {
		private String username;
		private String userpassword;
		private String userpasswordagain;
		
		public String getUsername() {
			return username;
		}
		
		public void setUsername(String username) {
				this.username = username;
		}
		
		
		
		
		public String getUserpassword() {
			return userpassword;
		}
		public void setUserpassword(String userpassword) {
			
				this.userpassword = userpassword;
			
		}



		public String getUserpasswordagain() {
			return userpasswordagain;
		}


		public void setUserpasswordagain(String userpasswordagain) {
				this.userpasswordagain = userpasswordagain;
			
		}
		
		
}

2. 登录系统

package book;

import java.util.ArrayList;

import java.util.Scanner;

public class Login_wudingfeng {
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ArrayList<Personinformation> array = new ArrayList<Personinformation>();
		Scanner input = new Scanner(System.in);
		for (;;) {
			System.out.println("-----欢迎使用登录注册系统-----");
			System.out.println("1.新用户注册\n2.用户登录\n3.查看信息\n4.退出系统");
			String select = input.next();
			if(select.equals("1")) {
				//注册页面
				zhuce_wudingfeng(array);
			}
			if (select.equals("2")) {
				//登录页面
				denglu_wudingfeng(array);
			}
			if (select.equals("3")) {
				//查看信息
				information_wudingfeng(array);
			}
			if (select.equals("4")) {
				//退出登录注册系统
				System.out.println("退出系统！");
				break;
			}
			if(!select.equals("1")&&!select.equals("2")&&!select.equals("3")&&!select.equals("4")) {
				System.out.println("请输入正确数字");
			}
		}
		
	}
	
		//欢迎使用注册系统
		public static void zhuce_wudingfeng(ArrayList<Personinformation> array) {
			Scanner in = new Scanner(System.in);
			Personinformation zc =new Personinformation();
			System.out.println("欢迎使用注册系统");
			for (;;) {
				System.out.print("请输入用户名:");
				 String name = in.next();
				if (name.length()>=3) {
					zc.setUsername(name);
					break;
				} else {
					System.out.println("用户名长度要求>=3,请重新输入用户名");
					
				}
			}
			
			String pass;
			for(;;) {
				System.out.print("请输入密码:");
				pass = in.next();
				if (pass.length()>=6) {
					zc.setUserpassword(pass);
					break;
				} else {
					System.out.println("密码长度要求>=6,请重新输入用密码");
					
				}
			}
			
			System.out.print("请再次输入密码:");
			String pass1 = in.next();
			for (;;) {
				if(pass1.equals(pass)) {
					System.out.println("新用户注册成功!");
					break;
				} else {
					System.out.println("注册失败!");
					return;
				}
			}
			array.add(zc);
			
		}
		//欢迎使用登录系统
		public static void denglu_wudingfeng(ArrayList<Personinformation> array) {

			Scanner in = new Scanner(System.in);
			Personinformation zc2 = new Personinformation();
			System.out.println("欢迎使用登录系统");
			int b = -1;
			System.out.print("请输入用户名:");
			String name2 = in.next();
		
				for(int a = 0 ;a < array.size() ;a++) {
					zc2 = array.get(a);
					if(zc2.getUsername().equals(name2)) {
						b = a;
						break;
					} 
				}
				if (b==-1) {
					System.out.println("用户名不存在！");
					return;
				}
				int n = 3 ;
			for(;;) {
				System.out.print("请输入密码:");
				String pass2 = in.next();
				if (pass2.equals(zc2.getUserpassword())) {
					System.out.println("登录成功，进入图书管理系统");
					denglujieko book = new book_wudingfeng();
					book.xitong();
					break;
				} else {
					System.out.println("密码错误！还有"+n+"次机会，请重新输入密码");
					n--;
					if(n<0) {
						System.out.println("3次密码输入有误，返回上一级");
						return;
					}
				}
			}
		}
		//欢迎进入信息查看系统
		public static void information_wudingfeng(ArrayList<Personinformation> array) {
			System.out.println("欢迎进入信息查看系统");
			if(array.size()!=0) {
				System.out.println("用户名"+"\t\t"+"密码");
				for(int a = 0 ;a <array.size();a++) {
					Personinformation in = array.get(a); 
					System.out.println(in.getUsername()+"\t\t"+in.getUserpassword());
				}
			}else {
				System.out.println("该系统未记入任和注册信息！");
			}
			
			
		}
}

3.创建 书籍类。 

package book;

public class bookinformation {
	private String booknumber;
	private String bookname;
	private String master;
	private String page ;
	private String bookform;
	private String number;
	public String getBooknumber() {
		return booknumber;
	}
	
	public void setBooknumber(String booknumber) {
		this.booknumber = booknumber;
	}
	public String getBookname() {
		return bookname;
	}
	public void setBookname(String bookn) {
		this.bookname = bookn;
	}
	public String getMaster() {
		return master;
	}
	public void setMaster(String master) {
		this.master = master;
	}
	
	public String getPage() {
		return page;
	}
	public void setPage(String page) {
		this.page = page;
	}
	public String getBookform() {
		return bookform;
	}
	public void setBookform(String bookform) {
		this.bookform = bookform;
	}
	public String getNumber() {
		return number;
	}
	public void setNumber(String number) {
		this.number = number;
	}
	
}

4. 图书管理系统 

package book;

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class book_wudingfeng implements denglujieko {
	//主系统
	public  void xitong() {
		// TODO Auto-generated method stub
		List<bookinformation> array = new ArrayList<bookinformation>();
		for (;;) {
			System.out.println("-----进入图书管理系统-----");
			System.out.println("1.查询\n2.新增\n3.删除\n4.修改图书\n5.返回登录系统");
			Scanner input= new Scanner(System.in);
			String select = input.next();
			if(select.equals("1")) {
				//查询图书
				booklook_wudingfeng(array);
			}
			if (select.equals("2")) {
				//新增图书
				addbook_wudingfeng(array);
			}
			if (select.equals("3")) {
				//删除图书
				deletebook_wudingfeng(array);
			}
			if(select.equals("4")) {
				//修改图书
				amendbook_wudingfeng(array);
			}

				System.out.println("返回登录系统！");
				return;

//				关闭JVM虚拟机

			}
		}
	}
