<div>Ok that helps a lot thank you. So let me make sure I
understand this. So our stations and state arrays from program
4, we can keep the same but make them arraylists? As in the
states arraylist shouldn't have duplicate states. It should have
the combined average temp for each state just like program 4?
And then the daily arraylist should have all 400,000+ daily
readings and the state it goes with? And then we sort that huge
arraylist by hottest and coldest and get the state station
number and avg state temp based on the hottest and coldest
reading?</div>

Generally you are correct. Keep the State.java and Station.java
objects as they are in Program 4, but in your program 5 store the
objects in ArrayLists. I STRONGLY recommend adding a third object
class, Daily.java, that looks a lot like Station.java but that has a
stationID and a daily average temp as instance variables. Each
time you process a line from the Daily.txt file you then crate a new
Daily object that holds the stationID and temp and then put that
object into your ArrayList. <br>
<br>
Once you have read all of the lines from the Daily.txt file you
should have the 400,000+ daily readings stored as objects (with
stationID and temp) in an ArrayList that you can sort. When you
print out the results you can recover the state that goes with the
stationID from your stations ArrayList (which holds Station objects)
and then use the state to recover the average temp from the
stateData (which holds State objects with average yearly temp info)
to get the average temp.<br>
<br>
All of you -- keep the questions coming so you can knock this out!
We will also dedicate most of classtime tomorrow to work on this.<br>
