Jbutton（ActionListener）可以启动静态方法吗？

Question

Im currently coding a Q&A Program, coincidentally called "Jarvis" (Iron Man AI).
The program isnt going to be that complex, so it just answers a few questions and will do simple things like start a song or open the explorer when I write a specific sentence.
I'm the complete opposite of a experienced Java-Programmer,
so I wrote all the important code into a JButton-Actionlistener started Method,
the rest of the code is just for design of the application window.
My problem right now is, that my Method,
public void actionPerformed(ActionEvent arg0)
which is started by my JButton ActionListener is just a "public void" Method, so that Im verry limited in my Code.
For example: for some things you need to have a
public static void main (String[]args)
method, but i dont know how to activate such a method by my actionlistener,
so when I try to start one of these with my actionlistener, there are errors everywhere and even the qickfix removed the "static" from the method.
(If you have any suggestions of making it more efficient, please let me know!)

However, here is my "Program" so far:

Answer 1

As noted above, you can call a static method from both a static and non-static context.

However, the method

public static void main (String[] args)

is the entry point to your program (as also noted by the comment above it), so it is unlikely you would want to call that from the action handler of your button. It will be called automatically when you launch java with your JarvisOS class as target (or run from your IDE, which I assume you use since you have quick fixes).

The signature of the main method is fixed, so whatever the quick fix suggests, do not remove the static keyword as that will prevent you from starting your program.

You will need to be more specific about the other "errors everywhere".

Answer 2

Yes, you could do

myButton.addActionListener(e -> myStaticMethod());

Good luck!
