How do I get a MessageBox like information window to appear in Java?
- by John McClane
I'm learning Java and I have no idea how to do this.
I dragged a button on the form in Netbeans, double clicked it and it created this event:
@Action
public void HelloClickMethod()
{
JOptionPane.showMessageDialog(this, "The message!", "This is supposed to be the MessageBox title.");
}
This is the exception the IDE brings up.
Cannot find symbol. Symbol: showMessageDialog()

Now I changed it to this:
@Action
public void HelloClickMethod()
{
JOptionPane.showMessageDialog(this, "The message!", "This is supposed to be the MessageBox title.",JOptionPane.ERROR_MESSAGE);
}
However the IDE is saying I have an error in the word 'this'. "Cannot find symbol". I don't understand. Why is it so dificult and why are the errors so esoteric. :P
