    Default calling this method

     public void changeWhole(double amount)
      {
        Pixel[] pixelArray = this.getPixels();
        Pixel pixel = null;
        int value = 0;
        int i = 0;
        while( i < pixelArray.length)
        {
          pixel = pixelArray[i];
          value = pixel.getBlue();
          pixel.setBlue((int) (value * 0.9));
          i++;
        }
      }
     
     
      public static void main(String[] args) 
      {
         String fileName = FileChooser.pickAFile();
         Picture pictObj = new Picture(fileName);
         pictObj.explore();
      }
    I want to call the changeWhole method in my main method but I don't have any idea on how to type it out.

    Default Re: calling this method

    FileChooser.pickAFile(); is a method call.
    pixel.getBlue(); is a method call.
    pizelArray[i]; is a more advanced method call.
    this.getPixels(); is a method call.
    i++; is a method call.

    With all the working examples you have, surely you have tried to call the changeWhole method in some way.
    What did you try?
    If nothing, try something now.
    ....
    What is the error message?
