Inner-anonymous classes can be hard to read.  But you avoid having an
extra source file that simply overrides one method on Authenticator. 
Creating the class in-line lets you leave the source where it makes the
most sense and avoid having misc. classes clog your project.

Correct code would look like this:

Authenticator objAuthenticator = new Authenticator(){
	//Insert above code here
}

This produces an object of type Authenticator that has the method
getPasswordAuthentication() overridden.
