Validating email address

[ravian]

I have a textfield on a frame and the user enters his email address in it. I want simple validation for it. I know how to do it using javascript on HTML pages but don't know how to do it on a frame.

Please help me out of this.

Cheers

Hi,
You can do the validation in swings same as Javascript using "Regular Expression". In java, you have two classes called "Pattern" and "Matcher". using which you can do this.

Example:-

String str=Regular Expression
String str2="Email Address to be validated"

Pattern p=Pattern.compile(str);
Matcher m=p.matcher(str2);

if(m.find()==true){}
else {}

Post Reply if u have doubts.

Thanks collins. I guess I have to explore regex API because I am not into regular expressions.

Thanks once again.
