Answer 1

import javax.swing.*;
import java.awt.*;

public class DogHouse extends JPanel {

    public void paint(Graphics g) {

        Graphics2D graph = (Graphics2D) g;

        /**Coordinates of the window center*/
        int cX = getWidth()/2;
        int cY = getHeight()/2;

        /**The first rectangle is home.*/
        graph.setColor(Color.GRAY);
        graph.fillRect(cX/2,2*cY/3,cX,cY);

        /**The second rectangle is the door.*/
        graph.setColor(Color.decode("#FAEBD7"));
        graph.fillRect(2*cX/3,cY,2*cX/3,3*cY/5);

        /**The roof is drawn in two lines.*/
        graph.setColor(Color.GRAY);
        graph.setStroke(new BasicStroke(5.0f));
        graph.drawLine(cX,cY/4,cX/10,cY);
        graph.drawLine(cX,cY/4,2*cX-cX/10,cY);

        /**The name of the dog is written in the middle above the door.
          *The font size changes as the window size changes.
          */
        String strDogName = "Justin Star Boy";
        graph.setFont(new Font("Veranda", Font.BOLD, cX/15));
        FontMetrics fm = graph.getFontMetrics();

        graph.setColor(Color.decode("#D2691E"));
        graph.drawString(strDogName, (getWidth() - fm.stringWidth(strDogName)) / 2,
                                 (getHeight() - fm.getHeight()) / 2 + fm.getAscent() - cY/6);

    }

    public static void main(String[] args) {
        JFrame fr = new JFrame("Dog House");

        fr.setSize(500, 500);
        fr.setLocationRelativeTo(null);
        fr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        fr.getContentPane().add(new DogHouse());

        fr.setVisible(true);
    }
}
