Hello,
I need help to know how to import classes.
Especially the javax.swing.JOptionPane
(My Java package(if that's the way it's called...?) is linked below. There is french(CA) notes in my program, but those are useless)
Here's my code :
(Beginning)
import javax.swing.JOptionPane;
public class Bonjour {
public static void main(String[] args) {
JOptionPane.showMessageDialog(null, "Voici mon premier programme java");
}
}
I would just like it show "Voici mon premier programme Java" in a window.
I have no error, but when I run it, nothings happen...
No window appears, nothing in console, anywhere....
Help me please, I'm so disappointed that my very first program is a total fail, and it should be so easy...
Thanks :)
Attachment: Bonjour.java

This forum is for helping to use Eclipse technology (the IDE and the frameworks), not for helping understand how to use some arbitrary Java framework. Have you tried things like setting a breakpoint and stepping into that method, or adding a print statement before and after the showMessageDialog to see if the code is executing at all?
