There is another way if your JDialog is being called from some other component...oh, lets say...a JFrame? &nbsp;<br />
<br />
The call to the JDialog is triggered somewhere in that code, or any other controlling class that you might have. &nbsp;They you only have to make that call directly after the control returns from the JDialog. &nbsp;There are many different possiblities. &nbsp;You can set a boolean variable to be changed if the proper actions were taken, if not correctly performed then trigger the new method--ie a JOptionPane message. &nbsp;<br />
<br />
I usually get rid of the JDialog with the 'dispose();' method, returning control to the calling class. &nbsp;<br />
<br />
But since you are wanting to close the program entirely with a system exit, then this is just food for thought.<br />

How to call a method when JDialog window is closing?

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
