Java编程——实现会员注册,要求用户名长度不小于3,密码长度不小于6,注册时两次输入密码必须相同 (字符串)

package register;

import java.util.Scanner;
public class Register 
{   String name;   String password;   String newPassword;   
public void nameExe()
  {     Scanner input
=new Scanner(System.in);     System.out.println("请输入用户名,密码和验证密码");     System.out.print("用户名:");     name=input.next();     System.out.print("密码:");     password=input.next();     System.out.print("验证密码:");     newPassword=input.next();     while(name.length()<3||(password.equals(newPassword)==false)||(password.length()<6))
    {       
if(name.length()<3)
      {         System.out.println(
"用户名不能小于3");       }       if((password.equals(newPassword)==false)||password.length()<6)
      {         System.out.println(
"两次输入密码不一样或密码不能小于6位");       }       System.out.println("\n"+"请重新输入");       System.out.print("用户名:");       name=input.next();       System.out.print("密码:");       password=input.next();       System.out.print("验证密码:");       newPassword=input.next();     }     System.out.println("注册成功!");   }
}

 

 

package register;

public class Verify extends Register
{
    public static void main(String[] args) 
    {
        Verify m1=new Verify();
        m1.nameExe();
    }
}
