    The start and stop times are not associated with the items. If two items are added before one is removed, the start time for the first item is lost. When the first item added is removed, its start time will be the time for the last item that was added, not the time that it was added.

    I'm talking about this statement:
    		startTime = System.currentTimeMillis(); // ***** GET TIME *****

    I don't see any use of the Timer class in the posted code.

    If the start time is NOT saved with the item, then there will only be one value in the program. There needs to be a starttime saved for EACH ITEM.

    Default Re: Average length of time for input/output

    So, I need another long to add all the time between inserts and removes together and then divide it by the outs?

            stopTime = System.currentTimeMillis(); // ****** GET TIME ******
            long measurement +=(stopTime-startTime);
    	totalTime = totalTime + measurement;

    Is this what you mean?

    No. There needs to be a class that holds the item's value and start time so that the start time is with the item.

    Any time you edit code, please post the new version with your new question so we all see the same code, especially if you go about it from a different angle.

    Paste the full text of any error messages with your code and question so we can easily offer help.



    :/ I guess there was another page I didn't read yet... Perhaps your problem has been fixed.
