How do I interrupt the thread I am currently running?

My Google skills seem to have failed me, so apologies if this is a simple question.

I simply want to interrupt ("kill" it I guess) the thread which I am currently running.

My class implements Runnable, and inside the run() method I want the thread to interrupt if a certain condition is met.

Cheers! :)

You have two choices:

return;

and most correct and recommended

Thread.currentThread().interrupt();

One other option depending on the context. Thread.interrupt will likely be better, but this one might be useful too by just introducing a cancel boolean inside your class. 

public class MyLongRunningTask implements Runnable
{
   private volatile boolean cancelled;

   public void run() {
      while (!cancelled) {
         System.out.println("Do something...");
      }
   }

   public void setCancelled(boolean cancelled) {
      this.cancelled = cancelled;
   }
}
