Graphics in Applet Program

The Graphics class is the abstract base class for all graphics contexts, which allow an application to draw on components realised on various devices as well as off-screen images. A Graphics object encapsulates the state information required for Java’s basic rendering operations.

Methods used in Graphics Applet program in Java

  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.
