Is there a way to save a JPanel's paintComponent contents into a .png file? Preferably with java.io or some other built-in library. Thanks.

Check out the [ImageIO class](http://docs.oracle.com/javase/7/docs/api/javax/imageio/ImageIO.html)'s methods, in particular the `write(...)` method. – Hovercraft Full Of Eels May 04 '13 at 02:33

create a java.awt.image.BufferedImage
get a java.awt.Graphics by BufferedImage.createGraphics()
Pass the Graphics to JPanel.paintComponent()
Use javax.imageio.ImageIO.write() to save it
