  3. public abstract void fillRect(int x, int y, int width, int height): is used to fill rectangle with the default color and specified width and height.
  4. public abstract void drawOval(int x, int y, int width, int height): is used to draw oval with the specified width and height.
  5. public abstract void fillOval(int x, int y, int width, int height): is used to fill oval with the default color and specified width and height.
  6. public abstract void drawLine(int x1, int y1, int x2, int y2): is used to draw line between the points(x1, y1) and (x2, y2).
  7. public abstract boolean drawImage(Image img, int x, int y, ImageObserver observer): is used draw the specified image.
  8. public abstract void drawArc(int x, int y, int width, int height, int startAngle, int arcAngle): is used draw a circular or elliptical arc.
  9. public abstract void fillArc(int x, int y, int width, int height, int startAngle, int arcAngle): is used to fill a circular or elliptical arc.
  10. public abstract void setColor(Color c): is used to set the graphics current color to the specified color.
  11. public abstract void setFont(Font font): is used to set the graphics current font to the specified font.

    2. import javax.swing.JFrame;
    3. public class DisplayGraphics extends Canvas{

    6.         setBackground(Color.WHITE);

    8.         g.drawOval(30,130,5060);
    9.         setForeground(Color.RED);
    10.         g.fillOval(130,130,5060);
    11.         g.drawArc(3020040,50,90,60);
    12.         g.fillArc(3013040,50,180,40);
    13.     }
    14.         public static void main(String[] args) {
    15.         DisplayGraphics m=new DisplayGraphics();
    16.         JFrame f=new JFrame();
    17.         f.add(m);
    18.         f.setSize(400,400);
    19.         //f.setLayout(null);
