Best way to create an array

Question

Im struggeling a little bit with arrays. My applications uses data stored in an array (res/array-xml), but I want the user to be able to create custom arraydata and store these in a file on the device. Or even better, download arraydata from the internet.

I haven't found out wether I should use XML with a custommade XMLParser or a flatfile with CSV. The use of a database is also an option, but that will most likely be added in version 2... ;-)

The arraydata is best organized in a two-dimentional array. The data looks like this;

name[0],name
name[1],name
name[2],name
address[0],streetname
address[1],streetname
address[2],streetname
city[0],name
city[1],name
city[2],name

Is there a nifty way to get this flatfile into an array looking like this:

array[0..2][0..2]name

Or, even better, a nifty way to read an XMLfile and get a array like this?

Or shuld I just start with this example and modify it to my needs?

Personally I wouldn't use a 2d array I would use Collections. They are easier to work with than arrays to parse XML.

You don't say whether you control the XML data from the internet. I assume that it's data you will create an distribute.

In that case, Java (and Android) has many different implementations of arrays and lists, most of which support serialization.

This Q&A should set you down the right path. Serializing and de-serializing is easy, and very useful, once you get the hang of it.
