How can I keep the selected state of a JCheckBox after closing and reopening the JFrame containing the JCheckBox?

Question

In a Java Swing application, I have two JFrames, one MainFrame and a 2nd JFrame with a JCheckBox and an OK JButton.

In the MainFrame there is an Edit JButton to open the 2nd JFrame.

When the 2nd JFrame opens, I select the JCheckBox to true and click OK JButton to close (dispose) the 2nd JFrame.

I need the JCheckBox to be selected when I reopen the 2nd JFrame.

However, when I open the 2nd JFrame again using the Edit JButton (in the MainFrame) I found the JCheckBox is unchecked.

When I select a JCheckBox and close the containing JFrame, I expect that JCheckBox to remain selected when reopening the containing JFrame.

Please see my two codes to review this further.

Answer 1

abraha Tekulu I typically avoid Java development and Desktop UI Apps in general. Therefore, I've not worked with Swing components before this question. 😉
