[JAVA] Maybe it can be used at a year-end party? Mosaic game code

Background and purpose

As the year-end party season approaches, the stress of newcomers who are forced to be secretaries in the middle is considerable. Maybe it can be used as a sideshow for a year-end party to reach out to such a newcomer. I created a mosaic game with Processing.

how to use

Click k on the keyboard to reduce the image mosaic Click j on your keyboard to enlarge the image mosaic.

PImage img;
MozImage moz;
float mozSize = 80;//Early mosaic size
boolean sizeUp = true;
boolean sizeDown = true;

void setup() {
  background(0);
  img = loadImage("Lion.PNG");//Image settings
  size(1143, 676);//Set canvas size to image size
  
  smooth();
  noStroke();
}

void draw() {  
  for (int i=0; i<width/mozSize; i++) {
    float x = mozSize * i;
    for (int j=0; j<height/mozSize; j++) {
      float y = mozSize * j;
      moz = new MozImage(int(x), int(y));
      moz.show();
    }
  }
}

void keyPressed() {
  if (sizeDown == true && key == 'k') {
    if(mozSize >10){
      mozSize -= 10;
    }else{
      mozSize = 1;
    }
    sizeDown = false;
  } else if (sizeUp == true && key == 'j') {
    mozSize += 10;
    sizeUp = false;
  }
}

void keyReleased() {
  sizeDown = true;
  sizeUp = true;
}

class MozImage {
  float x;
  float y;
  float r;
  MozImage(int _x, int _y) {
    x = _x;
    y = _y;
    r = mozSize;
  }
  void show() {
    color c = img.get(int(x), int(y));
    fill(c);
    noStroke();
    //ellipse(x,y,2*r,2*r);
    rect(x, y, r, r);
  }
}

Example of use:
