We have no idea what you're doing wrong currently. You may want to give us more information.

Thanks for replying sir,
Actually i dont know how to start with a code, i am thinking of using BufferedImage and tried of modifying the following code at Combine two images using Java - Open Source University Meetup .. but i am not getting the right output.. please give me guidance...

Construct a BufferedImage
Obtain its Graphics context
drawString the text

If you want more help, ask a specific question. Not "i dont know how to start"

If that's really your only problem, go through some tutorials. I find thwe ones on the Sun site good.

If I understand your question correctly, you just need to do something like this:

BufferedImage bi = ...;
Graphics2D g2d = ( Graphics2D ) bi.getGraphics();
g2d.setColor( Color.BLACK );
g2d.setFont( new Font( "arial", Font.PLAIN, 30 ) );
g2d.drawString( "Hello World!", bi.getWidth()/2, bi.getHeight()/2 ); // You can use FontMetrics and other classes to get string bounds
g2d.dispose(); // Don't forget to call dispose()!
