Constructor Details

SSLSocket

protected SSLSocket()
Initializes a new instance of Socket object without connecting to a remote host. This useful for subclasses of socket that might want this behavior.
Since:
1.1

SSLSocket

protected SSLSocket(String host,
                    int port)
            throws IOException,
                   UnknownHostException
Initializes a new instance of Socket and connects to the hostname and port specified as arguments.
Parameters:
host - The name of the host to connect to
port - The port number to connect to
Throws:
UnknownHostException - If the hostname cannot be resolved to a network address.
IOException - If an error occurs
SecurityException - If a security manager exists and its checkConnect method doesn't allow the operation

SSLSocket

protected SSLSocket(String host,
                    int port,
                    InetAddress localAddr,
                    int localPort)
            throws IOException,
                   UnknownHostException
Initializes a new instance of Socket that connects to the named host on the specified port and binds to the specified local address and port.
Parameters:
host - The name of the remote host to connect to.
port - The remote port to connect to.
localAddr - The local address to bind to.
localPort - The local port to bind to.
Throws:
SecurityException - If the SecurityManager exists and does not allow a connection to the specified host/port or binding to the specified local host/port.
IOException - If a connection error occurs.
Since:
1.1

SSLSocket

protected SSLSocket(InetAddress address,
                    int port)
            throws IOException
Initializes a new instance of Socket and connects to the address and port number specified as arguments.
Parameters:
address - The address to connect to
port - The port number to connect to
Throws:
IOException - If an error occurs
SecurityException - If a security manager exists and its checkConnect method doesn't allow the operation

SSLSocket

protected SSLSocket(InetAddress address,
                    int port,
                    InetAddress localAddr,
                    int localPort)
            throws IOException
Initializes a new instance of Socket and connects to the address and port number specified as arguments, plus binds to the specified local address and port.
Parameters:
address - The remote address to connect to
port - The remote port to connect to
localAddr - The local address to connect to
localPort - The local port to connect to
