如何在打开主 jframe 时关闭所有 jframe

Question

I made a desktop application with 3 frames { "login" , "Choice" , "name" }. the mainframe is "login" , and when you log in the choice frame appears that lets you choose a search method (I only use 1 frame "name" for this example) . Now when I log out from "Choice" , the "Choice" closes and the "login" frame appears, BUT the "name" frame gonna be still open. So How I close all the frames while opening the mainframe?

THIS IS MY FUNCTION:

    private void jLabel2MouseClicked(java.awt.event.MouseEvent evt) {                                     
    //log out
    login log=new login();
    log.setVisible(true);
    this.dispose();// this only close the Choice frame not all the frames
}

Login: enter image description here choice: enter image description here

Name: enter image description here
