String[] data=loadStrings("data.txt");

That will give you one String per line of the text file data.txt put in the data subdirectory of your sketch.

yes, that works but theres a problem i found in this : why does my program doesnt change when i change the text file? it seems it just read the txt file when i compile the ejecutable file... but what about if i need that my txt file is always changing and i need that processing can read when something changes in the txt file...?
any hint?

You could check each time the draw function is called for your data.
So each time you save your .txt file it'll be updated in your sketch.
(There might be a more gentle way of doing it tho)


Code:

 void setup(){
   //set things up here
 } 
 
 void draw(){
   //check for data
  String[] data=loadStrings("data.txt"); 
  println(data);
 }
