It will wait 5 seconds before processing the code inside the Runnable. Usually this will be used to repeat a task at regular intervals.

If I delay handler for 5 seconds,

1. will handler process all the code inside it during this time?
2. Or it will just wait for 5 seconds to process inside code?

 new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {

                //code

                }
            }, 5000);
