Retrieving values from a LinkedList
Nov 28th, 2006, 1:57pm  

Could someone please assist me by demonstrating how Processing can store values in a dynamic array. The following returns mismatched Object types.

LinkedList a = new LinkedList();
int[] b = {1, 2};
a.add(b);
b = a.get(0);
println(a.get(0)[0]);

When retrieving items from an object array (LinkedList) you need to cast them from the Object type (as they exist in the array) into the type you put into the array.

In your case an integer array (int[])
Code:

LinkedList a = new LinkedList();
a.add(new int [] {1, 2});
int [] temp = (int[])a.get(0);
println(temp);

Most folks these days are using ArrayList or Vector (Both linked lists with an added ability to control internal capacity for speed purposes, the difference with Vector is that it's synchronised between threads - uncommon in Processing applets).
