Displaying Graphics in Applet

java.awt.Graphics class provides many methods for graphics programming.

Commonly used methods of Graphics class:

  1. public abstract void drawString(String str, int x, int y): is used to draw the specified string.
  2. public void drawRect(int x, int y, int width, int height): draws a rectangle with the specified width and height.
  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.

Example of Graphics in applet:

  1. import java.applet.Applet;
  2. import java.awt.*;
  3. public class GraphicsDemo extends Applet{
  4. public void paint(Graphics g){
  5. g.setColor(Color.red);
  6. g.drawString(“Welcome”,5050);
  7. g.drawLine(20,30,20,300);
  8. g.drawRect(70,100,30,30);
  9. g.fillRect(170,100,30,30);
  10. g.drawOval(70,200,30,30);
  11. g.setColor(Color.pink);
  12. g.fillOval(170,200,30,30);
  13. g.drawArc(90,150,30,30,30,270);
  14. g.fillArc(270,150,30,30,0,180);
  15. }
  16. }
