How do I programmatically send ActionEvent to JButton?

Question

How do I programmatically send an ActionEvent (eg button pressed/ACTION_PERFORMED) to a JButton?

I know of:

button.doClick(

Even if you could, why would you want to? Usually when people want to do something like this, it means they haven't properly separated the concerns of the UI from business logic. Typically they want to invoke some logic that occurs in an ActionListener without needing the action to take place.

public void actionPerformed(ActionEvent ae) {
    //SomeLogic
}

//...

public void someOtherPlace() {
    //I want to invoke SomeLogic from here though!
}

But really the solution is to extract that logic from the ActionListener and invoke it from both the ActionListener and that second location:

public void someLogic() {
    //SomeLogic
}

public void actionPerformed(ActionEvent ae) {
    someLogic();
}

//...

public void someOtherPlace() {
    someLogic();
}
