I have to create an assignment using loops and conditionals... Ok so I created a 8x8 grid checkerboard, But, i want to make it white and black, how do I do that please help? The code Below is what i'm working with on processing. I've tried soo many things but i cant figure it out. I tried if statements and all that but I cant seem to get it.



int NumBars = 35;
int cols, rows;

void setup() {
  size(280,280); // 280/8 = 8x8 grid full screen. The size has to be divided by 8.
  cols = width/NumBars;  // height/35 - this makes the height go up the screen
  rows = height/NumBars; // width/35 - this makes it go across the screen
}

void draw() {
 
  // Begin loop for columns
  for (int i = 0; i < cols; i++) {  // Height
    // Begin loop for rows
    for (int j = 0; j < rows; j++) { //Width
     
      // Scaling up to draw a rectangle at (x,y)
      int x = i*NumBars; //  height
      int y = j*NumBars; // width
    
      stroke(0);
      // For every column and row, a rectangle is drawn at an (x,y) location scaled and sized by videoScale.
      rect(x,y,NumBars,NumBars);
     

     
    }
  }
}



please help thanks
