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.

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.
