  • This site is for narrowly-focused questions on a specific technical issue. This is much too broad. Servlet, mail, and executors have been covered in many other questions and answers. – Basil Bourque Aug 13 '18 at 09:10

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

  1. If you use IOC then you can declaration bean
  2. Second way simple executorService declaration how static variable;

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.
