Hi,

Once an array has been initialised at a certain size, how can you empty and change the size of the array? I'm working on this problem in a larger program, so I've written this simple bit of code to try and figure out how to do it. What I want it to do is set up an array of a particular size, and then whenever the mouse button is pressed, change the size of that array to the mouseX position. It doesn't seem to work, and I can't figure out what I'm doing wrong. Sorry, I've only been coding about two weeks...

1. int Asize = 100;
   int[] testarray = new int[Asize];
   
   void setup() {
     size(400, 400);
   }
   
   void draw() {
   }
   
   void mousePressed() {
     println("The previous array size was " + testarray.length);
     Asize = mouseX;
     expand(testarray, Asize);
     println("The new array size is " + testarray.length);
   }
   

Any help MUCH appreciated!
