Question

How to reload a form in a JFrame? I have two forms, form1 and form2:

1. form1 links to form2 using:

   new form2().show(); 
   this.setVisible(false);
   

2. form2 links to form1 is success

3. The problem is when form1 form2 links to existing data are not shown.

I want to ask is there any other way than setVisible() method because it seems just to hide it.

Answer 1

You can use CardLayout to switch between forms. This example navigates with buttons; this example navigates with a combo. You can make navigation conditional based on what filled on your form.

Addendum: Like a restart in pc, jframe exit and re-open again.

Although CardLayout is much more flexible, but you can always empty the Container, add the desired components and invoke validate()/repaint(), as shown here.
