Processing Randomized Building Drawing Window Issue

I’m reposting this as the code was not correct the first time I posted this. I got it all down up to this part. It looks like this.

but it should look like this.

Any Help with making it so the windows align to the buildings would be great as I am quite new to this. Thanks

int[] buildingHeights = new int[12];
int[] starXValues = new int[200];
int[] starYValues = new int[200];

void setup(){
 size(600,450);
 background(0);
}
void draw(){}
void drawAll(){
  fill(255);
  stroke(255);
  drawSky();
  drawBuildings();
}
void drawSky(){
  stroke(255);
  strokeWeight(1);
  ellipse(500,-20,150,150);
  for(int i = 0; i<starXValues.length; i++)
  point(starXValues[i],starYValues[i]);
}
void drawBuildings(){
  stroke(0);
  for(int i = 0; i<buildingHeights.length;i++){
    drawBuilding(i*50,height-buildingHeights[i]*50);
  }
}
void drawBuilding(int x, int y){
  fill(100);
  rect(x,height,50,-y);
  for(int i = 1; i < 7; i++){
    for(int j = 1; j < height/y; j++){
       int lights = (int)random(2);
       if(lights==1)
       fill(#ECFF27);
       else
       fill(255);
       rect(x*i,y*i,5,10);
    }
  }
}
void randomize(){
  for (int n = 0; n < starXValues.length; n++ ) 
    starXValues[n] = (int)random(width);  
  for (int n = 0; n < starYValues.length; n++ ) 
    starYValues[n] = (int)random(width);   
  for (int n = 0; n < buildingHeights.length; n++ ) 
    buildingHeights[n] = (int)random(8); 
    
}
void mousePressed(){
  background(0);
  randomize();
  drawAll();
}

Answer

You had a problem adjusting the windows x/y positions according to your building, I tried to fix it to look as close as possible to the example picture you showed

void drawBuilding(int x, int y){
  fill(100);
  rect(x,height,50,-y);
  for(int i = 1; i < 6; i++){
    for(int j = 1; j <= y/25; j++){
       int lights = (int)random(2);
       if(lights==1)
       fill(#ECFF27);
       else
       fill(0);
       
       rect(x+i*10-8,height-j*25+12,5,10);
    }
  }
}
