How to set a class as an argument?

Question

Java

Hello everyone
Tell me, who knows how to submit a class as an argument? Probably not quite correctly expressed the question, the example below explains:
I have a method that changes the listener for buttons:

void changeListeners(ArrayList<JButton> buttons, Object className) {
        ActionListener[] listeners;
        for (JButton btn:buttons) {
            listeners = btn.getActionListeners();
            for (ActionListener l:listeners) {
                btn.removeActionListener(l);
            }
            btn.addActionListener(new className.getClass()); //знаю что такая конструкция может все сломать
        }
    }

but since the new listeners are different, then, accordingly, you need to give the argument to the class that will be the listener.
Thanks

so easy to find

this.getClass().getClassLoader().loadClass("package.classname").newInstance();
