Creates an unconnected socket, specifying the type of proxy, if any, that should be used regardless of any other settings.

If there is a security manager, its checkConnect method is called with the proxy host address and port number as its arguments. This could result in a SecurityException.

Examples:

Socket s = new Socket(Proxy.NO_PROXY); will create a plain socket ignoring any other proxy configuration.
Socket s = new Socket(new Proxy(Proxy.Type.SOCKS, new InetSocketAddress("socks.mydom.com", 1080))); will create a socket connecting through the specified SOCKS proxy server.

Parameters:

proxy a Proxy object specifying what kind of proxying should be used.

Exceptions:

IllegalArgumentException if the proxy is of an invalid type or null.

SecurityException if a security manager is present and permission to connect to the proxy is denied.

Since: 1.5

`IllegalArgumentException`		if the proxy is of an invalid type or `null`.
`SecurityException`		if a security manager is present and permission to connect to the proxy is denied.
