Message Dialog

The code that you write calls a method of the Swing class JOptionPane.
JOptionPane offers a number of features, including specifying more than one button
and providing a text input area that the user can fill in. It is an easy way to show a
dialog box. For debugging message purposes, you only need its simplest format,
shown in this example:

JOptionPane.showMessageDialog(this,
   "The debugging message.",
   "Debug Message",
   JOptionPane.INFORMATION_MESSAGE);
}

Step 8. ... In the blank line between curly brackets, insert the following code:

Dialog1 myDialog = new Dialog1();
myDialog.show();

A variation on this technique ... as follows:

Dialog1 myDialog = new Dialog1(this, "My test dialog", true);
