How to kill a java thread?

Question

I google the solution for killing a java thread. And there exists two solutions:

1. set a flag
2. using Thread.interrupt

But both of them ar

Answer 1

I would put the call a third-party api which takes a long time into a Callable and then execute it with a SingleThreadExecutor specifying a timeout.

Following this approach, the thread will be killed if the call to third party API takes longer than timeOut, here is some code to exemplify what I am saying:

ExecutorService executor = Executors.newSingleThreadExecutor();
 try {
   //================= HERE ==================
   Future job = executor.submit(thirdPartyCallable);
   executor.awaitTermination(timeOut, TimeUnit.SECONDS);      
   if(!job.isDone())
     logger.debug("Long call to 3rd party API didn't finish");
   //=========================================
 } catch (Exception exc) {
     exc.printStackTrace();      
 } finally {
     if(!executor.isShutdown() )
       executor.shutdownNow();
 }

}  

private static Callable  thirdParytCallable = new Callable() {
  public Boolean call() throws Exception {
    //Call to long 3rd party API
    //.......
    for(long i = 0;i<99999991999999L;i++) {
      Thread.sleep(10L);// Emulates long call to 3rd party API
      System.out.print(".");
    }
    return Boolean.valueOf(true);//Data from 3rd party API
  }
};
