Calling this method

[antnas]

 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.

How about making the changeWhole method static and then:

public static void main(String[] args)
 {
    String fileName = FileChooser.pickAFile();
    Picture pictObj = new Picture(fileName);
    pictObj.explore();
    changeWhole(0); // 0 as amount variable is not used within the method
 }

OR create an object of your class (which you did not mention, so I call it XXX)

public static void main(String[] args)
{
String fileName = FileChooser.pickAFile();
Picture pictObj = new Picture(fileName);
pictObj.explore();

XXX main = new XXX();
main.changeWhole(0); // 0 as amount variable is not used within the method
}

How about making the changeWhole method static

And how do you propose to use this.getPixels() in a static method?

The correct approach is to create an instance of the class and invoke the method on that instance.
