Stop a thread?

[sci4me]

Hey guys. So, I have yet to truly know how to properly stop a thread. Thus, I have an example and I am wondering if I am stopping the thread the correct way. I would also like to know, can you call .start on a stopped thread to restart it?
Heres the example:

package com.sci;
 
import com.sci.rpi.api.RaspberryPi;
 
public class RPI implements Runnable
{
	private Thread thread;
	private boolean running;
 
	public RPI()
	{
                thread = new Thread(this);
	}
 
	public void onStartup() throws Exception
	{
		running = true;
		thread.start();
	}
 
	public void onShutdown() throws Exception
	{
		running = false;
		thread.join();
	}
 
	@Override
	public void run()
	{
		while(running)
		{
			//do things that are fun and useful 
		}
	}
}

You can "stop" thread by calling Thread.interrupt. Also, if you do want such a functionality, your while loop should look like while(!Thread.isInterrupted()). Or you should perform such check-ups in some other place regularly. And you cannot restart thread that was interrupted. Consider using Runnable if you want to start a similar thread in future.
