Can someone please help me?

Hi, I created this static method...

private static void errorFlag(MyGrid grid) {
      grid.setColor(0, 0, Color.RED);
      grid.setColor(0, (grid.getWd()-1), Color.RED);
      grid.setColor((grid.getHt()-1), (grid.getWd()-1), Color.RED);
      grid.setColor((grid.getHt()-1), 0, Color.RED);
    }
    // the errorFlag4 method creates an error flag of size 4.
    private static void errorFlag4(MyGrid grid) {
      grid.setColor(0, 0, Color.RED);
      grid.setColor(0, 7, Color.RED);
      grid.setColor(3, 0, Color.RED);
      grid.setColor(3, 7, Color.RED); 
    }
 

And this might sound really stupid, but I have no idea how to call it. This is the code I'm trying to use it in.....

public static void drawFlag(MyGrid grid, int countryCode) {
 
        int height = grid.getHt();
        int width = grid.getWd();
        int col;
        int row;
 
        //What happens if the user enters 1.
        if (countryCode == 1) {
 
            //What happens if the user inputs a height that's a multiple of 3.
            if (height % 3 == 0) {
                //Colors the top 1/3 of the flag red.    
                for (col = 0; col < width; col++) {
                    for (row = 0; row < (height / 3); row++) {
                        grid.setColor(row, col, Color.RED);
                    }
                }
                //Colors the bottom 1/3 of the flag red.
                for (col = 0; col < width; col++) {
                    for (row = (height*2) / 3; row < (height); row++) {
                        grid.setColor(row, col, Color.RED);
                    }
                }
            }
            else if (height % 3 != 0 && height >= 4 && height <= 30) {
                /*Creates error flag (red dot in each corner), with 
                 * user inputed height*/
                grid.setColor(0, 0, Color.RED);
                grid.setColor(0, width-1, Color.RED);
                grid.setColor(height-1, 0, Color.RED);
                grid.setColor(height-1, width-1, Color.RED);
            }
            else if (height % 3 != 0 && height < 4 && height > 30) {
                /*Creates error flag (red dot in each corner), with 
                 * height = 4*/
                XXXXXXXXXXXXXXXXXX-Where I want to call it-XXXXXXXXXX
            }
        }
 
 

Can someone please tell me how I would call those methods? Thank you in advance!

Can someone please tell me how I would call those methods? Thank you in advance!

Did you write those methods yourself? Anyway, just look at the method's signature
(its parameter list) and its return type. They tell you exactly how to call them
and what return value (and type) to expect.

kind regards,
