how can i stop the block method DatagramSocket.receive() in a thread

Question

Answer 1

Close the socket, which will stop the receive() call from blocking. If you first set a closed flag then in the catch (IOException) block you can safely ignore the exception if the flag is set. (You could probably also use isClosed() method on DatagramSocket instead of a flag)
