Stop waiting for user input in java

Question

The scenario is like that: One thread is handling with the UI, and the second is handling the logic in the backgorund. Both are working simultaneously.

If some event occurred, and I want that the first thread will stop to wait for user command and will execute other task.

Is it possible to do it?

Answer 1

It depends on your implementation and architecuture, but generally, you can't stop waiting for user input. For instance, calls to System.in are effectively translated to system calls which cannot be cancelled.
