Do you meant that you just want to validate whether a String forms a valid e-mail address? If so, just use a regular expression.

i woul dlike to know whether it forms a valid email address. eg it has a @ sign etc

[ArchAngel]

Like I said - use a regular expression. If you only want to be sure the String has an '@' symbol you can use the String's indexOf(...) method.
