How would I go about turning this bouncing ball code into code to show multiple random balls?

coding94

Im trying to make code based off of my previous code. I want to make random balls come into the screen and then leave the screen from random directions without bouncing. How would I go about doing this?

This is what i have:

float circleX;
float xspeed=3;

void setup(){
  size(400,400);
  circleX=0;
}
void draw(){
  background(51);
  fill(102);
  stroke(255);
  ellipse(circleX,height/2,32,32);

  circleX = circleX + xspeed;

  if(circleX>width || circleX<0){
    xspeed=xspeed*-1.1;
  }
}
