Import an array to arduino?

Hi, I'm using this code here from Anthony Mattox on visualizing sound with processing. I want to take it a step further and and write another code that uses the data collected from processing and download it to Arduino to make a Music-responsive LED arrangement.

Here's the code that i got from the site

import krister.Ess.*;

FFT myfft;
AudioInput myinput;
int bufferSize=512;

void setup() {
  size(532,400);
  frameRate(30);
  background(255);
  noStroke();
  fill(0);

  Ess.start(this);
  myinput=new AudioInput(bufferSize);
  myfft=new FFT(bufferSize*2);
  myinput.start();

  myfft.damp(.3);
  myfft.equalizer(true);
  myfft.limits(.005,.05);
}

void draw() {
  background(255);
  for (int i=0; i<bufferSize;i++) {
    rect(i+10,390,1,myfft.spectrum[i]*-400);
  }
}

public void audioInputData(AudioInput theInput) {
  myfft.getSpectrum(myinput);
}

So basically this codes acts as a spectrum a nalyzer by using the microphone as the input. I want to import myfft.spectrum[i] and use it in another program and download that new program into arduino. So is there like an import command that i need to write in my second program, or do I just need to put both files in the same sketch folder?

I know this is just a simple matter of importing an array, but unfortunately I didn't really pay much attention during my Java class,(which I deeply regret).
