Struts Iterator best Object usage

[A knibbs]

Hi all I am now getting a bit more comfortable with the iterator in Struts, and it's time for me to design some structures to store my data in.

I want to be able to put multiple strings and iterate over parts of each of the string sets.
So for example if I have productName, productDesc and productPrice, I was thinking of storing these things in an object, and them putting all of these objects in a data structure (this is the part that I am curious about what would make the best sense). When I stated that I want to iterate over parts of the list I was thinking that I could use the length and the offset values in the iterate function to implement paging. Does this seem reasonable, and can what I want to do with respect to the collection of objects work with the iterator ?

Hopefully that made enough sense if not please let me know and i'll try to explain it more clearly.

Cheers

Recommended datastructure: Plain vanilla java.util.List (probably ArrayList)

Alternatively if you are going to be looking up the products by id, storing them in a Map (hashmap) keyed by id is a good way to go. With struts you will probably have to make sure that the "key" values are Strings, not Integer objects.

I am using array list, but the part that has me a little confused is how I am supposed to iterate through all of the values at the same time. Suppose I have elements 1,2 and 3. I then place those into an object and then put the object into the array. the part that I am confused on is how does one pull out the individual components from the object- can a method call be used ?

thanks once again.

The other thought that came to mind was maintaining multiple Arraylists but that just seemed too ugly to work with.

Seems that all I had to do was to make accessors for all the variables and then just add them in. I am quite impressed by how simple it actually was. I am enjoying struts more and more as I learn it.
