Timeout on connect to socket using NIO SocketChannel [duplicate]

Answer 1

You're doing this wrong.

1. Create an unconnected SocketChannel and do a timed connect in blocking mode.

OR

2. Use a Selector in non-blocking mode. Register the channel for OP_CONNECT and select. When it becomes connectable, call finishConnect(), and if it returns true deregister OP_CONNECT and proceed with the I/O. If it returns false, keep selecting. If it throws an exception, give up of the connection, it has failed. Use the select timeout. Not a spin loop.
