ActionListener in main

[stuckonjava]

lets say in my class App I have an instance variable of button ok. in the class constructor is instantiated and linked to a button("ok").

Now in the main method, could I do App.ok.addActionListenernew ActionListener(){etc}???

If so what is this called?

That's an anonymous inner class. And while this can be done, and I have no issue with using an anonymous inner class here, you have other problems with your example -- you would not want to expose your variables in this way, nor should they be static. Better that the ok variable not be public, and not be static. Better to give the App a public method that will allow you to do this with an App instance variable.

Could you provide a concrete example in the form of an SSCCE?
