i've been trying to do some validation on email format from a html form, i need to
read " @email.com.cc" and prompt to user that it is not a valid email format which
should be "[EMAIL PROTECTED]" instead.
how do i do this ? is this the norm of email validation ???
below is my program, when i run i have nullpointer exception at
MemberBean.testEmail
thank you for your attentions and inputs.
********************************************
import java.util.*;
import java.lang.*;
class MemberBean {
double Day;
double Month;
double Year;
String Email;
String DOB;
char e1, e2, e3;
StringTokenizer T;
MemberBean (double day, double month, double year, String email, String dob) {
Day = day;
Month = month;
Year = year;
Email = email;
DOB = dob;
}
boolean testDate() {
if(Month >=1&&Month <=12){
if(Day >=1&&Day <=31){
System.out.println("Date Validation Passed");
}else
System.out.println("Invalid Day");
}else
System.out.println("Invalid Month");
return false;
}
void testEmail(){
int l = 0;
String stringArray[] = new String[20];
StringBuffer sbuf = new StringBuffer(Email ); // create a StringBuffer
int s[ ] = new int[ 20 ]; // array to hold length of
// each string
// Build a StringBuffer with all the Strings concatenated
for (int i = 0; i < 20; i++ )
{
s[ i ] = stringArray[ i ].length(); // save the length of each
l += s[ i ]; // and the total length
sbuf.append(stringArray[ i ]); // concatenate the next string
}
String result = new String( sbuf ); // convert to String
char ch[ ] = new char[ l ]; // create the char array
ch = result.toCharArray( ); // and convert to char array
System.out.println("Email "+ ch[l]);
//*************************************************
// if(ch!='@'){
// System.out.println("Email Validation passed "+ ch);
// S.pop();
// }else
// System.out.println("Invalid Charater "+ ch);
}
}
class verifyBean {
public static void main(String args[]) {
MemberBean verify1 = new MemberBean(1,12,00, "[EMAIL PROTECTED]", "12/08/78");
MemberBean verify2 = new MemberBean(32,01,00, "[EMAIL PROTECTED]", "22/02/76");
boolean date = false;
date = verify1.testDate();
verify1.testEmail();
date = verify2.testDate();
}
}
