How can we get the block height using fabric sdk java?

Thanks, but what happens if the peers and orderers have already join a channel that it is not useful anymore?

Hi Nikos, There is no way to delete a channel. But as you spin up new peers and ordering nodes, you can select which channels they join. If you do not join them to channels that you do not want to
