Looping over URLs, stupid problem...

Hi,

i am working with processing for not so long now, and i am kinda stuck with this...

I have 2 urls, where i want to loop through.

Putting them in an array is something i do not quite understand..

The urls are about stock data, and with Minim i convert them to Hertz.

Now i have put the 2 urls in the void draw() function, but now it will only put out the last url as sound.

I want to have the first url for 2 seconds and then the second url for 2 seconds.

Quite ugly how it looks now, but i was just trying..

CAN ANYBODY HELP ME??

thanks in advance!!

Code:

import ddf.minim.*;

import ddf.minim.signals.*;

ArrayList tags;

AudioOutput outSine;

AudioOutput outSaw;

AudioOutput outSine2;
