Write a program in java that reads allows the user to enter a URL address, read the content from this user specified URL (if it is an invalid URL, handle this exception MalformedURLException and output invalid URL).

The EmailAddresses.txt contains list of email addresses (one per line), you may assume that a valid email in the regular expression is ^(.+)@(.+)[.](.+)$ That is, before @, there are at least one character, after @, there are one or more characters, followed by ., and then followed by one or more characters.

The program then reads the email addresses (IOException also needs to be handled while reading the email addresses from url stream) and prints out valid email addresses.
