| ↳ | 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.
