@SohelaS16717900 When you say, "validate email id in regular expression format ", What exactly are you trying to refer here, can you explain it bit further..!

You can search for a regular expression on the internet and test it on regex101.com to see if it validates all the email addresses you want to validate.
One of the sources you could use is O'Reilly.
Then you can simply use a function / edit validate to validate the value.
if (theValue == null || theValue.trim().equals(""))
{
return false;
}
else
{
String regExp = "YOUR_REGEXP_STRING";
java.util.regex.Pattern ptHandle = java.util.regex.Pattern.compile(regExp);
java.util.regex.Matcher maHandle = ptHandle.matcher(theValue);
maHandle.matches() ? true : false;
}
