Problem with missing ball (foo)

I have a sketch (see below) where a ball moves. When I tested it, everything seems to work but now the ball has gone off the screen to the right somewhere. How do I get my ball back?

Ball[] balls = new Ball[1];


void setup() {
    size(400, 400);
  
balls[0] = new Ball(40, 127); // diameter and colour
}

void draw() {
    background(255);
  for (int i = 0; i < balls.length; i++) {
    balls[i].display();
    balls[i].move();

  }

  
}

class Ball {
  float dia;
  float x;
  float y; 
  float col;
  float xspeed;
  float yspeed;
  float r;

  Ball (float tempD, float tempC) {
    x = random(0+dia, width-dia);
    y = random(0+dia, height-dia);
    dia = tempD;
    col = tempC;
    r = dia/2;
    xspeed = 1.0;
    yspeed = 0.0;
  }

  void display() {
    noStroke();
    fill(col);
    ellipse(x, y, dia, dia);
  }

  void move() {

    x = x + xspeed;
    y = y + yspeed;
  }


}

You can check for the screen border and then reverse the direction of the movement

Remark

color is not really float. Either use int or even color.

Thanks. This was my very poor attempt to make an April’s fool joke. I liked the idea that someone could be foolish enough to try to get their ball back. Looks like the joke is on me!

Noted about color not being a float.
