i need to validate that an inserted email address contains "@" and "." without a regular expression. Can somebody to give me "java code" and "structure chart" examples please?
I suspect you're after something like:
if (!address.contains("@") || !address.contains("."))
{
// Handle bad address
}
EDIT: This is far from a complete validation, of course. It's barely even the start of validation - but hopefully this will get you going with the particular case you wanted to handle.
