5. URLs and URIs

URIs

URLs Relative URLs

The URL Class

Creating New URLs

Constructing a URL from a string Constructing a URL from its component parts Constructing relative URLs Other sources of URL objects

Retrieving Data from a URL

public final InputStream openStream() throws IOException public URLConnection openConnection() throws IOException public final Object getContent() throws IOException public final Object getContent(Class[] classes) throws IOException

Splitting a URL into Pieces

public String getProtocol() public String getHost() public int getPort() public int getDefaultPort() public String getFile() public String getPath() public String getRef() public String getQuery() public String getUserInfo() public String getAuthority()

Equality and Comparison Conversion

The URI Class

x-www-form-urlencoded

URLEncoder URLDecoder

Proxies

System Properties The Proxy Class The ProxySelector Class

Communicating with Server-Side Programs Through GET Accessing Password-Protected Sites

The Authenticator Class The PasswordAuthentication Class The JPasswordField Class

6. HTTP

The Protocol

Keep-Alive

HTTP Methods The Request Body Cookies

CookieManager CookieStore

7. URLConnections

Opening URLConnections Reading Data from a Server Reading the Header

Retrieving Specific Header Fields

public String getContentType() public int getContentLength() public String getContentEncoding() public long getDate() public long getExpiration() public long getLastModified()

Retrieving Arbitrary Header Fields

public String getHeaderField(String name) public String getHeaderFieldKey(int n) public String getHeaderField(int n) public long getHeaderFieldDate(String name, long default) public int getHeaderFieldInt(String name, int default)

Caches

Web Cache for Java

Configuring the Connection

protected URL url protected boolean connected protected boolean allowUserInteraction protected boolean doInput protected boolean doOutput protected boolean ifModifiedSince protected boolean useCaches Timeouts

Configuring the Client Request HTTP Header Writing Data to a Server Security Considerations for URLConnections Guessing MIME Media Types HttpURLConnection

The Request Method

HEAD DELETE PUT OPTIONS TRACE

Disconnecting from the Server Handling Server Responses

Error conditions Redirects

Readiness Selection

The Selector Class The SelectionKey Class

12. UDP

The UDP Protocol UDP Clients UDP Servers The DatagramPacket Class

The Constructors

Constructors for receiving datagrams Constructors for sending datagrams

The get Methods

public InetAddress getAddress() public int getPort() public SocketAddress getSocketAddress() public byte[] getData() public int getLength() public int getOffset()

The setter Methods

public void setData(byte[] data) public void setData(byte[] data, int offset, int length) public void setAddress(InetAddress remote) public void setPort(int port) public void setAddress(SocketAddress remote) public void setLength(int length)
