What is "working" for this program?
What happens instead?
Copy and paste your error messages so we don't have to
tire out our crystal balls.
You should place your program in a package, rather than the
"default" (empty) package.
import javax.swing.JFrame;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.Continer;
^
You should get a compilation error on this import.
class Jframe {
Get in the habit of declaring classes 'public', and not naming them so
similarly to standard API types.
public static void main(String[] args) {
JFrame frame = new JFrame();
You failed to put the GUI work on the Event Dispatch Thread (EDT).
ImageIcon icon = new ImageIcon(puffin.jpg);
^
This line should raise a compilation error.
JLabel label = new JLable (icon);
^
This line should raise a compilation error.
Container contentPane = frame.getContentPane();
contentPane.add(label);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
}
You are getting compilation errors that tell you exactly where you are being
careless.
Use 'invokeLater()' to do GUI things (like defining your frame and all that).
Doing GUI off the EDT and doing non-GUI on the EDT are the twin sins of Swing.
Repent your sins.
