Question

write some lines of Java code that create a Screen object. Then call its clear method if (and only if) its number of pixels is greater than two million. (Don’t worry about things being logical here; the goal is only to write something that is syntactically correct—i.e., that would compile if we typed it in.)

Answer 1

Please find the required program below along with the comments and output:

class Screen {

    private int pixels;

    public Screen(int pixels) { //Constructor
        this.pixels = pixels;
    }


    public void clear(){
        if(this.pixels > 2000000) {
            System.out.println("Screen Cleared!!");
        }
    }

    public int getPixels() {    //getter
        return pixels;
    }

    public void setPixels(int pixels) { //setter
        this.pixels = pixels;
    }
}


class Main {

    public static void main(String[] args) {

        Screen screen = new Screen(2100000);    //Creating an object of Screen class

        screen.clear(); //calling clear method of screen object
    }
}
