Question

Write a program which asks the user to submit personal information and then by using methods to check them.

-user id
-password
-re enter password
-email adress
-name
-email address
-city
-state
-zipcode
-tel number

Write each of thes methods in your class.

1.) Method checking that no strings in the array are empty. If one is empty, return false, otherwise return true.
2.) Method returning the number of characters in user id.
3.) Method checking if the two Strings representing the passwords are identical. If they are, it returns true; if not, it returns false.

4.) Method checking if the String representing the email actually containes  @ character and contains one or more periods after the @ character . If it does then the method returns true; otherwise, it return false.

Write a client class to test all these methods in your class.

Write comments to help me understand the code. Thank you.

Explanation / Answer

import java.util.*;

class ClientClass{

//Method to return length of the userid, lenght is an int so it is defined as int type

public int uidLength(String inUid){

String userId = inUid;

return userId.length();

}

// checks and retruns false if any input is empty else true

public boolean checkLengthAll(String[] a){

int j=0;

//if length of any of the input is 0, it increase the value of j by 1

for(int i=0;i<9;i++){

if(a[i].length() == 0){

j++;

}

i++;

}

// if the j is not 0 (i.e increased by the above check) then it returns false else true

if(j>0)

return false;

else

return true;

}

//checks if both passwords are same, returns true else false

public boolean pwdMatchCheck(String passwd1,String passwd2){

//equals() method check for the content of the string

//where as == check for the address of the string

if(passwd1.equals(passwd2))

return true;

else

return false;

}

//e-mail validation

public boolean validateEmail(String mailid){

//The below is the regular expression for checking the e-mail string--- this is common for all

String EMAIL_REGEX = "^[\w-_\.+]*[\w-_\.]\@([\w]+\.)+[\w]+[\w]$";

String email1 = mailid;

//matches method in string class matches the string with the given regular expession

//it returns true if the string matches with the regular exp else false

Boolean b = email1.matches(EMAIL_REGEX);

return b;

}

public static void main(String args[]){

//Below variables are to take the inputs from the user

String uid,pwd,repwd,name,email,city,state,zipcode,phone;

//This array is to save all the user inputs - as per your request

String[] arrayAll = new String[9];

//Scanner is used to read the user inputs from the console

Scanner s = new Scanner(System.in);

//Below lines of code is to take the inputs from the users

System.out.println("Enter username:");

uid = s.nextLine();

System.out.println("Enter password:");

pwd = s.nextLine();

System.out.println("Enter re-password:");

repwd = s.nextLine();

System.out.println("Enter Name:");

name = s.nextLine();

System.out.println("Enter email:");

email = s.nextLine();

System.out.println("Enter City:");

city= s.nextLine();

System.out.println("Enter State:");

state= s.nextLine();

System.out.println("Enter zipcode:");

zipcode = s.nextLine();

System.out.println("Enter phone:");

phone = s.nextLine();

//Below code is to initialize the array with the user inputs

arrayAll[0] = uid;

arrayAll[1] = pwd;

arrayAll[2] = repwd;

arrayAll[3] = name;

arrayAll[4] = email;

arrayAll[5] = city;

arrayAll[6] = state;

arrayAll[7] = zipcode;

arrayAll[8] = phone;

//Create an object for your class

ClientClass cc = new ClientClass();

//get the length of the userid using the function

int uidCount = cc.uidLength(uid);

System.out.println("Length of the userid : "+uidCount);

//check if any of the inputs are empty

boolean isEmptyCheck = cc.checkLengthAll(arrayAll);

System.out.println("Return False if anyone of the input is Empty : "+isEmptyCheck);

//check if password are identical

boolean arePwdSame = cc.pwdMatchCheck(pwd,repwd);

System.out.println("Return True if both passwords are same : "+arePwdSame);

//check if the user has entered correct e-mail

boolean emailCheck = cc.validateEmail(email);

System.out.println("Returns True if the e-mail is valid : "+emailCheck);

}

}
