trouble with arrays for my paddle game

so i'm making a game and i want to bounce 3 balls off a paddle. I just, somewhat, learned how to use Arrays but i keep getting error messages. If anyone could help me out with this I would really appreciate it!

float[] circle=new float[3];

float[] circX=new float[3];

float[] circY=new float[3];

float[] vy=new float[3];

float[] vx=new float[3];

int w=500;

float d=40;

void setup()

{

  for(int i=0;i<3;i++){

   circX[i]=random(d/2,w-d/2);

   circY[i]=random(d/2,w-d/2);

   vx[i]=random(5,10);

   vy[i]=random(5,10);

   fill(255);

  }

  size(w,w);

}

//float circX=200;

//float circY=100;

//float velocityX=5;

//float velocityY=0;

int hit=0;

int miss=0;

void draw()

{

  if(mousePressed)

  {

   hit=0; miss=0;

  }

  float paddle=1000/(miss+10);

  if(miss>10){

   text("GAME OVER:");

  }

  if(circX[i]<0 || circX[i]>width) velocityX=-velocityX;

  if(circY[i]>height)

  {

   velocityY=-velocityY;

   float distance = abs(mouseX-circX[i]);

   if(distance<paddle) hit +=1;

   else miss= miss+1;

  }

   else velocityY = velocityY+ 1;



  circX[i]=circX[i]+velocityX;

  circY[i]=circY[i]+velocityY;



  background(100,100,100);

  fill(100,200,50);

  ellipse(circX[i],circY[i],50,50);

  fill(255);

  rect(mouseX-paddle,height-10,2*paddle,20);



  fill(0);

  text("hit:" + hit,10,20);

  text("miss:" + miss,10,40);

}

need help with a game please

so i want to make a game where the mouse has to dodge balls that are bouncing around the screen. so far i am trying to just get 1 ball to bounce around but it just sits there. if someone could help me out that would be great! here is the code so far:

int velocityX;

int currentX,currentY;

void setup()

{

  size(300,300);

  background(150);

  velocityX=1;

  currentX=0;

  currentY=height/2;

}

void draw()

{

  background(150);

  ellipse(currentX,currentY,20,20);

  currentX=currentX=velocityX;

  if(currentX>width)

  {

   velocityX=velocityX*-1;

  }

  if(currentX<0)

  {

   velocityX=velocityX*-1;

  }

}
