ArrayIndexoutofbounds with image objects

I got array out of bounds issues.
when i try to put images as objects in my code
( simply rect primitives in the ancient code );
i have
ERROR MESSAGE Arrayoutofboundsexception coordinate out of bounds
when i try the function display() without img.resize the code work.
so it's only about img.resize
i tried img.resize(xpos,ypos); and also img.resize(frameCount,frameCount) but the result is the same
could you explain me more about this array index out of bounds?
is it about " if (xpos > width) {
xpos = 0; ? "
best regards

void draw() {
background(255);
for(int i = myCar.size()-1;i>=0;i--){
Car ball = (Car) myCar.get(i);
ball.move();
ball.display();
if(frameCount>160){frameCount=ceil(cos(frameCount));}
}

myCar.add(new Car(color(frameCount), mouseX, mouseY,random(30),1));
