ActionEvent in Java

Question

I recently started learning Java and i came across a statement including (ActionEvent e ). What does e mean and is it a standard? Or can we use anything else in place of e? Because when I change this by any other variable, it still works.

Is e an instance of ActionEvent?

Answer 1

It's just a parameter, so you can replace it with any letter or word you want. It's so common though, since most of the automatically generated actionevents would generate the parameter 'e'.
