How to create a jbutton to save the jpanel as a jpeg??

Hello, I am a beginner of java.
I made a class to print out the calendar with jpanel. And I don't know how to create a jbutton to save the calendar as a jpg for the users.
Does anyone can tell me how to do that? Thanks in advance!!!

Button is easy.

Code:

---

JButton button = new JButton("Click Me!");

---

You will need to add an action listener to the button to tell java what to do when the user clicks it. Here is a tutorial for buttons: tutorial

Now as far as saving a jpeg... How are you displaying a calendar? Are you drawing on a JPanel with Java2D? You can draw to a BufferedImage and use ImageIO to write that in your desired format.

Work on one step at a time. Because when comes to a button (actually any control) there are a lot to learn, specially with actions listeners. So you better do some considerable amount of work on it.

Thank you for the help, I now have a clear direction to do that:(happy):
