Making a game for class were balls fall from the top of the screen at random x variables and have slightly different speeds. I have everything figured out but 1 thing:

I need to figure out how to make it so when a ball is popped (when a ball hits the pad) the points value is displayed and floats to the top.I am rather new to processing and any help would be greatly appreciated.
ArrayList balls;
int ballRadius = 25;
float level = 1;
int score = 0;
float ballspop = 0;
void setup(){

  size (650, 700);
  fill(0);
  smooth();
 
  strokeWeight(4);
  PFont font = loadFont("ComicSansMS-Bold-24.vlw");
  textFont(font);
  balls = new ArrayList();
 
  for (int i = 0; i < level*2; i++){
         balls.add(new Ball(random(15,width-15), random(-300,0), ballRadius));       
  }
}

void draw(){
 
  background(255);
  frameRate(45);
  fill(0);
  rect(mouseX, height-10, 50,10);
  triangle((mouseX)+18,height, (mouseX)+25, height-40, (mouseX)+32, height);
  text("Score: " + score, 10,30);
  text("Level: " + level, width-150,30);
 
 
      
           if (balls.size() == 0) {
      
          text ("popped "+(ballspop/(level*2)*100 +"%") , 0 , height/2 + 50);
          if ((ballspop/(level*2)*100)>= 50) text ("Click to start next level", 0, height/2);
         
          else if ((ballspop/(level*2)*100)< 50) {
          text ("Casfadsfad", 0, height/2);
          }
      }
for (int i = balls.size()-1; i >= 0; i--) {
    Ball ball = (Ball) balls.get(i);
    ball.move();
    ball.display();

    if(mouseX > ball.x-50 && mouseX+32 < ball.x+50 && ball.y > height-40){
      score= score +50 - ball.bounceCount*10;
      balls.remove(i);
      ballspop= ballspop+1;
     
  }
   else if ( ball.bounceCount> 5) balls.remove(i);
  }
 }

        for (int i = 0; i < level*2; i++){balls.add(new Ball(random(15,width-15), random(-300,0), ballRadius)); }}
 }
