Java validation with regular expression

Hi

I need to validate a string such that only numbers, alphabets, -, _, . is allowed and the below mentioned code works fine.

if( ! l_name.matches("[A-Za-z0-9._-]+" ) ) {

// do stuff when a valid name is found

}

But i need to modify the above regex such that it should also allow space in the name. Any idea how to do that?

Thanks in advance.
