CacheResponse CacheResponse is used for getting resource from the ResponseCache. 
ContentHandler This class converts the content of a certain format into a Java type Object. 
CookieHandler This class is ready for managing a stateful cookie with HTTP protocol  
DatagramPacket This class models a datagram packet to be sent or received. 
DatagramSocket This class models a socket for sending & receiving datagram packets. 
DatagramSocketImpl The abstract superclass of datagram & multicast socket implementations. 
HttpURLConnection This abstract subclass of URLConnection defines method for managing HTTP connection according to the description given by RFC 2068 
Inet4Address  
Inet6Address  
InetAddress The Internet Protocol (IP) address class. 
InetSocketAddress  
JarURLConnection This class establishes a connection to a URL using the jar protocol. 
MulticastSocket This class models a multicast socket for sending & receiving datagram packets to a multicast group.

Proxy This class is about proxy setting. 
ProxySelector

Selects applicable proxies when connecting to network resouce represented by a URI. 
ResponseCache ResponseCache implements URLConnection caches. 
SecureCacheResponse A secure cache response, which is orignally retrieved through secure ways. 
ServerSocket ServerSocket create connections between 'host' and 'client' machines. 
Socket This class represents sockets to be used in connection-oriented (streaming) protocols.

Proxy.Type The proxy type, includes DIRECT, HTTP and SOCKS. 

Exceptions

BindException A BindException is thrown when a process cannot bind a local address/port, either because it is already bound or reserved by the OS. 
ConnectException This ConnectException is thrown when a connection cannot be established to a remote host/port, because for instance a server was not listening. 
HttpRetryException The exception to be thrown when a request cannot be retried. 
MalformedURLException This exception is thrown when a program attempts to create an URL from an incorrect specification. 
NoRouteToHostException The NoRouteToHostException may be thrown when attempting to connect to a remote machine and because of network fault or firewall, no route can be established. 
PortUnreachableException  
ProtocolException An attempt to connect to a socket of the wrong type (stream or nonstream) will trigger this exception. 
SocketException This SocketException may be thrown during socket creation or setting options, and is the superclass of all other socket related exceptions. 
SocketTimeoutException  
UnknownHostException This UnknownHostException is thrown when an IP address resolution is attempted and no host or resolver may be found. 
UnknownServiceException This UnknownServiceException is thrown when a particular service requested isn't support by the URL. 
URISyntaxException Represents an exception that occurred during parsing of a URI.
