    Default Calculating when the condition is during a time frame

    I Am writing my first big java project, and I have a fairly simple question.

    How can I calculate (using java.util.Calendar) whether a condition is during a space of time, say whether or not its during school hours.

    This is what i have so far...

    private void autoSound() {
    		  Calendar schoolStart = Calendar.getInstance();
    		  Calendar schoolEnd = Calendar.getInstance();
    		  schoolStart.clear();
    		  schoolEnd.clear();
    		  schoolStart.set(year, month, day, 7, 30);
    		  schoolEnd.set(year, month, day, 18, 25); //14
    		  if(soundy != 2) {
    			  return;
    		  }
    		  else {  
    		  if(current.before(schoolStart) == true || current.after(schoolEnd) == true) { //TODO: Fix during school calculation
    				  sound = true;
    			  }
    			  else {
    				  sound = false;
    			  }
    		  System.out.println(sound);
    	  }
    	 }


    Current is uptated like so just before this...


     private void advanceTime() {
    			Calendar Now = Calendar.getInstance();
    			year = Now.get(Calendar.YEAR);
    			day = Now.get(Calendar.DATE);
    			month = Now.get(Calendar.MONTH)+ 1;
    			hour = Now.get(Calendar.HOUR);
    			min = Now.get(Calendar.MINUTE);
    			days1 = Now.get(Calendar.DAY_OF_WEEK);
    			current.clear();
    			current.set(year, month, day, hour, min);
    			if(hour == 0) {
    				hour = 12;
    			}
    		}

    Default Re: Calculating when the condition is during a time frame

    So you need a method which tells you when a specified time is before some period's end time and after that period's start time? Hmmm, I think there are enough clues that a person reading the API doc for Calendar might be able to reasonably quickly find an answer...
