Q:

Time based actions or texts

I am trying to make an app for students, and in the home screen of the app I would like to display a message like "Hey! Good Morning" and it should change to "Hey!Good evening" when it is after 15:00hrs of a day and so on.
How can I achieve this ?

      Calendar c = Calendar.getInstance();
        int timeOfDay = c.get(Calendar.HOUR_OF_DAY);

        if(timeOfDay >= 0 && timeOfDay < 12){
            Toast.makeText(this, "Good Morning", Toast.LENGTH_SHORT).show();        
        }else if(timeOfDay >= 12 && timeOfDay < 16){
            Toast.makeText(this, "Good Afternoon", Toast.LENGTH_SHORT).show();
        }else if(timeOfDay >= 16 && timeOfDay < 21){
            Toast.makeText(this, "Good Evening", Toast.LENGTH_SHORT).show();
        }else if(timeOfDay >= 21 && timeOfDay < 24){
            Toast.makeText(this, "Good Night", Toast.LENGTH_SHORT).show(); 
}
