↳ | java.net.Authenticator |
An implementation of this class is able to obtain authentication information
for a connection in several ways. For this purpose it has to set the default
authenticator which extends Authenticator
by setDefault(Authenticator a)
. Then it should override getPasswordAuthentication()
which dictates how the authentication info is
obtained. Usually, it prompts the user for the required input.
