Load Something From Network Using Urlconnection In Addition To Readablebytechannel, Inward Thread

Posted on

Last illustration demo “Load something from Internet using URLConnection as well as BufferedReader, inward Thread“. Here is simply about other illustration using java.nio.channels.ReadableByteChannel.

Read operations are synchronous on a ReadableByteChannel, that is, if a read is already inward progress on the channel thus subsequent reads volition block until the outset read completes. It is undefined whether non-read operations volition block.
