// Example: 2D Array size(200,200); int cols = width; int rows = height;

 // Declare 2D array int[][] myArray = new int[cols][rows]; 

// Initialize 2D array values 

for (int i = 0; i < cols; i++) 

{ for (int j = 0; j < rows; j++) 

{ myArray[i][j] = int(random(255)); // This is the part!

 } }

// Draw points for (int i = 0; i < cols; i++) 

{ for (int j = 0; j < rows; j++) 

{ stroke(myArray[i][j]); point(i,j); }

 }

Please help. Thank you ever so much.
