I'm a new programmer and I'm having issues when I compile the following code:
import java.awt.*;
import java.awt.event.*;
import java.swing.*;
public class HelloWorld{
public static void main(String[] args){
int UserExit = JOptionPane.showConfirmDialog(null, "Do you really want to exit?", "Confirmation", JOptionPane.YES_NO_OPTION);
if (UserExit == JOptionPane.YES_OPTION) {
JOptionPane.showMessageDialog(null, "Goodbye!");
}
else {
JOptionPane.showMessageDialog(null, "Too late my friend!");
System.exit(0);
}
System.exit(0);
}
}
I have checked it many times but cannot find the mistake. Cygwin doesn't show the mistake and blames something different every time. I use cygwin as the compilation tool and my OS is Windows 8.1 x64 Bit.
Any help would be very welcome.
EDIT I use javac to compile code in Java, I meant I use cygwin as it's platform. I apologize.
EDIT The compiler was continiously "blaming" the libraries, the mistake was a wrongly typed class. Thanks to @kagmole and @RealSkeptic for helping me out :)
The swing
components are inside javax
, not java
.
Correct your imports by:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*; // <- Here
By the way, you should avoid global imports, and just import what you want like this:
import javax.swing.JOptionPane;
