Hi Thanks for your reply,
I am able to create JPG file but its not displaying text in the image.


public static void main(String[] args)
{
int width = 200;
int height = 100;

// Create a buffered image in which to draw
BufferedImage bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);

// Create a graphics contents on the buffered image
Graphics2D g2d = bufferedImage.createGraphics();

// Draw graphics
g2d.setColor(Color.white);
g2d.fillRect(0, 0, width, height);

g2d.setColor(Color.black);
g2d.drawString("Sample-Text", 0, 0);
RenderedImage rendImage = bufferedImage;
try {
// Save as JPEG
File file = new File("newimage.jpg");
ImageIO.write(rendImage, "jpg", file);
} catch (IOException e) {
}


// Graphics context no longer needed so dispose it
g2d.dispose();

// return bufferedImage;

}

Have a look at the API documentation for java.awt.Graphics. The x,y position arguments for drawString is the baseline of the text, not the upper left-hand corner. You can probably see the tail of the "p" at the top of your image.
 
It is sorta covered in the JavaRanch Style Guide.
