How to close an attached JFrame without closing parent class?
So, I have a JFrame in Main.java. In the class, I open the psvm (public static void main) of BlueCard.java like so: BlueCard.main(new String {""});. That works great and it executes a JFrame in that class.
However, when the JFrame in BlueCard.java is closed, both that and Main.java close. I don't want this. I want it to be independent of each other (without needing multiple JARs). Currently what I'm doing is when the user clicks to close BlueCard.java, it hides it and to the user it appears that everything has returned to normal.
Hiding the JFrame does not close that class however, and it remains there. Suppose somebody opened and closed 200 BlueCard.java files. Then you'd definitely be taking up unnecessary resources.
I saw somebody try frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); over at Close one JFrame without closing another? but as far as I know, closing the JFrame without exiting the code won't exit the code.
Is this a correct assumption, or does frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); actually work for this purpose? If not, how can I exit BlueCard.java without exiting Main.java (attempts like System.exit(0); close both).
