scanner blocking thread close
in a project im working on i have a client with a sender and receiver thread. When the server send the quit command im also sending the clients the "quit" message which should intterupt their sender and receiver threads. The receiver ends just fine but the sender (that has the scanner) is stuck waiting for the next line. What's the appropriate way to handle this? i tried closing the senders' scanner in the receiver among other things but nothing worked

Warning: abusing this will result in moderative actions taken against you.The
Scanner#nextLine won't finish until something is entered
it doesn't care about interruption
What you can do is close the scanner from the other thread
or which thread is the problem?

Warning: abusing this will result in moderative actions taken against you.If i try closing the sender thread drom the reciever nothing happens because the interrupt function gets stuck wating for the sender's scanner to close/recieve input First
I didn't say closing the other thread but closing the scanner
So you could add a
close() method to the receiver class or whatever that closes the Scanner
and the sender could call that or similarI did try that and i still had the same issue
I think I might have confused sender with receiver but whatever
Can you show that attempt and what exactly gets stuck?
I switched to using a buffered reader since its nextline function isnt blocking and that fixed it
BufferedReader#nextLine should be blocking normally - not sure what you mean but if it works, I guess it's ok:shrugging:
