JS-style alert box in java

Question

What's the Java Swing counterpart for the JavaScript alert() popup (if there is one)?

Are you referring to a [JOptionPane](http://docs.oracle.com/javase/7/docs/api/javax/swing/JOptionPane.html)? — Hovercraft Full Of Eels, Jun 16 '12 at 17:16

An basic way to accomplish such a popup is to use JOptionPane.showMessageDialog, see here.

JOptionPane.showMessageDialog(frame, "here comes the text.");   
// assumes frame to be a reference to the desired parent frame

How would I make that pane pop up (e.g. when a button is clicked, what code do I use to handle the event?)? – Bluefire Jun 16 '12 at 17:36

@Bluefire You may attach an `ActionListener` to your `JButton`, [see here](http://docs.oracle.com/javase/tutorial/uiswing/components/button.html). – Howard Jun 16 '12 at 17:44

Think you are looking for JOptionPanes but here is a good description of the different dialogs: http://docs.oracle.com/javase/tutorial/uiswing/components/dialog.html
