Please try this

ExecutorService es = Executors.newSingleThreadExecutor();
es.submit(new Runnable() {
       @Override public void run() 
       {
             try{
                while(true);
             }catch(InterruptException){
                Thread.currentThread().interrupt();
             }
        }

}); es.shutdownNow();
