How to start/stop/restart a thread in Java?

Once a thread stops you cannot restart it. However, there is nothing stopping you from creating and starting a new thread.

Option 1: Create a new thread rather than trying to restart.

Option 2: Instead of letting the thread stop, have it wait and then when it receives notification you can allow it to do work again. This way the thread never stops and will never need to be restarted.

Edit based on comment:

To “kill” the thread you can do something like the following.

yourThread.setIsTerminating(true); // tell the thread to stop
yourThread.join(); // wait for the thread to stop
