Create an interactive Java program that asks a user for some text of interest and then displays the first email address found in that text. (This is the basis for one of the programs that spammers use to mine text, such as email messages, Web pages, and blogs, to find email addresses they can then add to their lists of people to spam.) For our purposes, an email address is composed of an "@" and the two maximal-length strings with no embedded whitespace surrounding that "@". If there is no email address in the text, then the program should display just an "@".
Construct the class EmailAddress.java.
