ArrayList Problem
I am using and Arraylist for sor soil samples because I don't know the number of samples and the depth of each sample. I am having a problem setting up my Arraylist and would appreciate some help.
In general the sample can be handled with a two diminsional array.
int[][] layerdepth = new int[][]; // where layerdepth[sample number
unknow][depth unknow]
int[][] watercapity = new int[][]; // where water capacity[sample number
unknow][depth unknow]
I thought I could add this to an Arraylist By:
ArrayList asoildata = new Arraylist;
asoildata.add(sample number, layerdepth);
But it will not work. I need to retrieve data by sample number, and suggestions would be appreciated.
Thanks...Ronnie

There aren't really multidimensional arrays in Java, just arrays of arrays. So you should get the desired behaviour with an ArrayList of ArrayLists (though without the convenient regular array notation).
