You can use ExecutorService executorService = Executors.newFixedThreadPool(threadNumber); . There threadNumber is concurrent use threads.

ExecutorService executorService = Executors.newFixedThreadPool(threadNumber);

You can use it like this

if(cond1)
executorService.execute(new Runnable()
@Override
public void run()
sendmail(firstcond);

);
else
executorService.execute(new Runnable()
@Override
public void run()
sendmail(secondcond);

);



Do not forget put this executorService.shutdown(); to web server shutdown listener.

executorService.shutdown();
