how to efficiently create string representation of multiple checkboxes

[navrsalemile]

Hi all,

I have 10 strings representing checkboxes (states) from GUI like:

String str1;
...
String str10;

I want to construct one string that represents selection of states out of these in such a way that if particular string is null or not "" then it should be concatenated into that string, otherwise skipped.
I am wondering what is the most efficient way to do that besides if-the-else?

thanks,

I don't think that a concatenation of strings is efficient. To be sincere, it just make no sense for me.

Can you provide more details about what you're trying to do?

Cheers,

I added all strings to list using add() and then in a loop I used string buffer to append if not null and not "".
So I should get something like this as a result:

"str2-str4-str10"

which means user selected checkboxes 2, 4 and 10

I guess I could have used <html:multibox> and get collection directly but not sure how to do it

thanks,
--mile

I am not sure what you are trying to do. From my understanding, you want to have ten checkboxs, and if a user select few of them, then a concatenation of string is displayed. Am I right?

I think you could make a checkbox array, then you just need one loop to find which one is ticked.

my String representation would be "0101000001".

What about a boolean array?
