Dynamically changing Variable name

[AMP]

Hello,
I have ArrayLists that are Channel1, Channel 2......Channel1 6
I want to access them with a (for int s=1;s<17;s++) loop, but I dont
know how to do this:
"Channel+s"
Any help,
Thanks
Mike

You shold almost certainly be using an array, a list or a dictionary
instead. Why do you feel you *want* to have 16 different variables
rather than one?

Variable names are not known at run time. That is a basic principle of
compiled programming languages. (In a language with reflection, such as C#,
it may be possible to retrieve a variable name, but not to change it.)

What you want is an array of ArrayLists: Channel[0][...etc...],
Channel[1][...etc...], and so on.

Actually the data started out as Arrays and I am finding ArrayLists
allow me to clean the data easier.
I have 12 boards with 16 channels on each board.The amount of data
changes between channels and boards.
I should still be able to use some kind of "for statenent to do my
cleansing on a "Channel+i" basis.
Right?
Thanks

I think you missed that AMP wrote "an array of ArrayLists."
If you wanted, though, you could also have "an ArrayList of ArrayLists."

1. Create a new ArrayList called Temp
2. Add Channel1 to it, add Channel2 to it, ....
3. Do a loop on Temp, processing each channel in turn
4. Toss Temp, unless you want to keep it
