You can't change the code manually(That means by typing..). You have to change the property values of the JFrame. Goto Design widow of the frame. Then you can see property toolbox in a corner. You can change the properties of the JFrame (such as defalutCloseOperation..) from there.

And remember that, This is not overriding..!!

Are you using the Netbean's GUI code generator thing? I highly recommend you don't, except for fast "sample" demos.

When you say "go back to previous menu screen when user close department window", is the department window a JDialog modal popup? Is the menu screen part of the main JFrame window?

Yes , menu screen is jframe and in the jframe i am using menu bar when i run the program And click on departments from menu new department form open
One approach is add exit button in all forms so when click on exit i show menu screen but this is not my teacher want he said on exit department form menu screen appear
Netbeans. Generated code which is uneditAble and i know from properties panel i can change on exit property but
It it for departments form how to display menu screen? When exit the department form?

Is Departments from a JFrame or JDialog..?? If it is a Frame, insert a public method called setParent(JFrame parent) in Department form.

public class Department extend JFrame{
    private JFrame parent;
  
    public void setParent(JFrame parent){
        this.parent = parent;
    }
}

In menu screen, write this inside the department menu actionPerformed method.

Department d = new Department();
d.setParent(this);
d.setVisible(true);
setVisible(false);

Override windowClosing(...) method in Department form and insert,

parent.setVisible(true);

The defaultCloseOperation of Department form should be DISPOSE_ON_CLOSE..

If Department is a JDialog, you can do this easily. Refer JDialog in API. You will be able to find how to do..
