Examples of java.net.Socket.bind()

java.net.Socket.bind()
Binds the socket to a local address.
If the address is null, then the system will pick up an ephemeral port and a valid local address to bind the socket. @param bindpoint the SocketAddress to bind to @throws IOException if the bind operation fails, or if the socketis already bound. @throws IllegalArgumentException if bindpoint is aSocketAddress subclass not supported by this socket @since 1.4 @see #isBound
