Question

I have a main JFrame which consists of 3 small JPanel which are switched on the basis of selection by the user.

The problem is that I have to save the data inserted into JPanel into the database but I am unable to access the elements of the JPanel directly. So how do I accept those.

The entry in DB is done when the ACCEPT button is clicked in the main frame.
Please help

if(Selected==Credit Card){
    Select Credit Card Panel;
    }
if(Selected==Debit Card){
    Select Debit Card Panel;
    }
if(Selected==Cash on Delivery){
    Select Cash on Delivery Panel;
    }



onAccept(){
    if(Selected==Credit Card){
get data from Credit Card panel and store in Database; (variables like cc number, cvv)
}

if(Selected==Debit Card){
get data from Debit Card panel and store in Database;
}

if(Selected==Cash on Delivery){
get data from Cash on Delivery Card panel and store in Database;
}
    }

Answer 1

Have each of your 3 panels implement the same interface:

public interface DataStorer {
    public void storeDataInDatabase();
}

Then, when the accept button is clicked, call this:

DataStorer selectedPanel = (DataStorer) theDisplayedPanel;
selectedPanel.storeDataInDatabase();
