Displays morning, afternoon, evening, and evening messages based on time in Java

What do I want to do:

Display message based on

Good morning (12:00 ~ 12:00) > good noon (12:00 to 4:00) > good evening (4:00 to 9:00) > good night (9:00 to 6:00)

Code:

I use the 24-hour format to get this logic

private void getTimeFromAndroid() {
        Date dt = new Date();
        int hours = dt.getHours();
        int min = dt.getMinutes();

        if(hours>=1 || hours<=12){
            Toast.makeText(this,"Good Morning",Toast.LENGTH_SHORT).show();
        }else if(hours>=12 || hours<=16){
            Toast.makeText(this,"Good Afternoon",Toast.LENGTH_SHORT).show();
        }else if(hours>=16 || hours<=21){
            Toast.makeText(this,"Good Evening",Toast.LENGTH_SHORT).show();
        }else if(hours>=21 || hours<=24){
            Toast.makeText(this,"Good Night",Toast.LENGTH_SHORT).show();
        }
    }

Question:

Is this the best way, if none is the best way

Solution

You should do this:

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

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