1初期化画面

package   2;

import java.util.Date;
import java.util.HashSet;
import java.util.Scanner;

public class UserRegister {
     
 public static HashSet<User> USER_DATA=new HashSet<User>();//    
 public static void main(String[] args) {
     
	initData();//       
	
	Scanner scan=new Scanner(System.in);
	System.out.println("      :");
	String userName = scan.nextLine();
	
	System.out.println("       :");
	String password =scan.nextLine();
	
	System.out.println("       ：");
	String repassword =scan.nextLine();
	
	System.out.println("    ：");
	String birthday =scan.nextLine();
	
	System.out.println("    ：");
	String telNumber=scan.nextLine();
	
	System.out.println("    ");
	String email =scan.nextLine();
	//      ，        
	CheckInfo checkInfo =new CheckInfo(USER_DATA);
	String rsult=checkInfo.checkAction(userName,password,
			repassword,birthday,telNumber,email);
	System.out.println("    "+rsult);
}
 //     ，           
private static void initData() {
     
	// TODO Auto-generated method stub
    User user1=new User("  ","zz,123",new Date(),"18810319240","[email protected]");
    User user2=new User("  ","zz,123",new Date(),"18618121193","[email protected]");
    USER_DATA.add(user1);
    USER_DATA.add(user2);
}
}

2、データパッケージと書き換え

package   2;

import java.util.Date;

public class User {
     
	private String userName;//    
	private String password;//   
	private Date birthday;//     
	private String telNumber;//     
	private String email;

	public User() {
     
		super();
		// TODO Auto-generated constructor stub
	}
	public User(String userName, String password, Date birthday, String telNumber, String email) {
     
		super();
		this.userName = userName;
		this.password = password;
		this.birthday = birthday;
		this.telNumber = telNumber;
		this.email = email;
	}

	@Override
	public int hashCode() {
     
		return userName.hashCode();
	}

	@Override
	public boolean equals(Object obj) {
     
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		User other = (User) obj;
		if (userName == null) {
     
			if (other.userName != null)
				return false;
		} else if (!userName.equals(other.userName))
			return false;
		return true;
	}

}

3、データ検査

package   2;

import java.text.DateFormat;
import java.text.ParseException;

	}

	//       ，        ;
	public String checkAction(String userName, String password, String repassword, String birthday, String telNumber,

					}
				}
			}
			if(telNumber.length()!=11) {
     
				result.append("         11\r
");
				state=2;

				DateFormat format=new SimpleDateFormat("yyyy-MM-dd");
				Date dateBirthday =null;
				try {
     
					dateBirthday =format.parse(birthday) ;
				} catch (ParseException e) {

					e.printStackTrace();
				}
			    User newUser=new User(userName,repassword,
			    		dateBirthday,telNumber,email);
			    if(!(USER_DATA.add(newUser))) {
     
			    	result.append("    ");
			    	state=2;
