i have written the folowing code and when i run it i get an error : arrayIndexOutOfBoundsExcepton: 0
1. import oscP5.*;
  import netP5.*;
  import processing.serial.*;
2. Serial arduinoPort;
  OscP5 oscP5;
3. int motor1 = 0;
  int motor2 = 0;
  int [] m1 = new int [2];
  int [] m2 = new int [2];
4. void setup()
  {
  size(200,100);
  noStroke();
  oscP5 = new OscP5(this,8000);
  arduinoPort = new Serial(this, Serial.list()[0], 9600);
  }
5. void oscEvent(OscMessage theOscMessage)
  {
  {
      String addr = theOscMessage.addrPattern();
      if(addr.indexOf("/1/toggle") !=-1){
        int i = int((addr.charAt(9) )) - 0x30;
        m1[i] = int(theOscMessage.get(0).floatValue());
  }
  }
  {
      String addr = theOscMessage.addrPattern();
      if(addr.indexOf("/2/toggle") !=-1){
        int i = int((addr.charAt(9) )) - 0x30;
        m2[i] = int(theOscMessage.get(0).floatValue());
  }
  }
  }
6. void draw() {
  background(225);
7.    if(m1[1] == 0){
      arduinoPort.write("l");
      motor1 = 0;
  }
  if(m1[1] == 1){
  arduinoPort.write("L");
  motor1 = 255;
  }
  fill(motor1,0,0);
     ellipse(50, 50, 50, 50);
  
     if(m2[1] == 0){
      arduinoPort.write("l");
      motor2 = 0;
  }
  if(m2[1] == 1){
  arduinoPort.write("L");
  motor1 = 255;
  }
  fill(motor2,0,0);
     ellipse(50, 100, 50, 50);
  }
