Question

Complete the code MyImage and test in your own main
Public class MyImage {
    private char[][] pixels;
    private int imageSize;

    //constructor
    public MyImage(int imageSize) {
        pixels = new char[imageSize][imageSize];
        for (int i = 0; i < imageSize; ++i) {
            for (int j = 0; j < imageSize; ++j) {
                pixels[i][j] = '.';
            }
        }
    }

    //print image
    public void print(){
        //add your code

    }

    //draw a triangle with '*'
    public void drawTriangle() {
        //add your code

    }

    //draw a diamond with '*'
    public void drawDiamond() {
        //add your code

    }

}
