This class represents an Internet Protocol version 4 (IPv4) address.

This class represents an Internet Protocol version 6 (IPv6) address.

This class represents an Internet Protocol (IP) address.

This class implements an IP Socket Address (IP address + port number) It can also be a pair (hostname + port number), in which case an attempt will be made to resolve the hostname.

This class represents a Network Interface address.

A URL Connection to a Java ARchive (JAR) file or an entry in a JAR file.

Thrown to indicate that a malformed URL has occurred.

A MulticastSocket is a datagram socket that is convenient for sending and receiving IP multicast datagrams.

This class represents a Network Interface.

Signals that an error occurred while attempting to connect a socket to a remote address and port.

The class PasswordAuthentication is a data holder that is used by Authenticator.

Signals that an ICMP Port Unreachable message has been received on a connected datagram.

Thrown to indicate that there is an error in the underlying protocol, such as a TCP error.

Represents a family of communication protocols.

This class represents a proxy setting, typically a type (http, socks) and a socket address.

Selects the proxy server to use, if any, when connecting to the network resource referenced by a URL.

Represents implementations of URLConnection caches.

Represents a cache response originally retrieved through secure means, such as TLS.

This class implements server sockets.

This class implements client sockets (also called just "sockets").

This class represents a Socket Address with no protocol attachment.

Thrown to indicate that there is an error creating or accessing a Socket.

The abstract class SocketImpl is a common superclass of all classes that actually implement sockets.

This interface defines a factory for socket implementations.

A socket option associated with a socket.

Interface of methods to get/set socket options.

Thrown to indicate that an unknown service exception has occurred.

Represents a Uniform Resource Identifier (URI) reference.

Checked exception thrown to indicate that a string could not be parsed as a URI reference.

Class URL represents a Uniform Resource Locator, a pointer to a "resource" on the World Wide Web.

This class loader is used to load classes and resources from a search path of URLs referring to both JAR files and directories.

The abstract class URLConnection is the superclass of all classes that represent a communications link between the application and a URL.
