Let's make this REALLY simple.  Since you already wrote a method in 
program four which essentially did the bubble sort -- which we said in 
class today should run at roughly the same order as the Selection sort 
-- then you can just use the same sorting method you used in program 
four.  You will have to modify it to work with ArrayLists, but that 
should not be terribly difficult (although it will require some thinking 
about how ArrayLists operate).

You are sorting the ArrayList based on the hottest and coldest daily 
temperatures.   Remember, each temperature in the daily file is the 
average temperature for that particular station on that particular 
day.   Sorting an array of objects this big with either the selection 
sort of the bubble sort will take some time.
