Good to you I am making an aplicaicon with several JFrames and in one of them there is a confirmation window, then suppose the following thing; I have: JF1. JF2. JD1.

Instance JF2 from a button belonging to JF1 and from there instancio JD1 and I want that at the push of a button, JD1 and JF are closed and reopened JF1 .

The problem here is that JF2 was installed in JF1 and I do not know how to close it from JD1

You should use the setVisible(boolean) instance method that each JFrame contains. That is, in the button's events method (which would close JF1 and JD1 ) you should set with setVisible(boolean) what windows to show and which ones not.

The JF2 that is static . in JF1 you would call it JF2.setVisible (true), and in JD1 JF2.setVisible (false) or JF2.dispose ();
