Array Comparisons in Program

[cmdolcet69]

Currently i write to an arraylist of (n) lenght. After I collect that
arraylist i have always been dumping the arraylist to a file (excel
spread). This time however i have been asked to create up to 4
arrayslist hold there value and compare all 4 array so that they have
unique values.

Example logic is below:
if my first array holds all unique values then i end
array1(5,6,7,8, 9)

if my first array doesn't hold unique value i go another round and get
array2 then compare.
array1(3,4,5,5, 6,7)
array2(2,7,7,8, 9,1)
i would then take array1 and array2 and average them out to get
another avgarrylist that would hold unique values.


Can someon please help. How can i do this?

You could use a hashtable - if you add duplicates into a hashtable you'll
get an exception.

Can i do it with jsut comparing the arrays, i need the simplest and
quickest way of doing this.
i read somthing about an arraylist.sort? How would that work? I want
sort through my original arraylist and see if any duplicte are in the
arraylist.

Using a hash table is the simplest.

arraylist.

You'll have to compare each element in the list?

Hi,

Assuming that you have version 2005.

Create a generic list instead of an arraylist, that you can do as well in
version 2003, however than you need some casting.
