• How to save a BufferedImage as a File 5 answers

I have a JFrame, on it are several JComponents and one of the components (say MyComponent) is where things get drawn. How can I save what is drawn on this image onto a file. I've been told that a BufferedImage is what I need, but how exactly can I do it. I did try looking at some questions on BufferedImage and it only got me confused.

I only want the code that saves MyComponent into an image file so that I can study and experiment with it.
