error in these two(addActionListener) in Main class line 36,37
"The method addActionListener(ActionListener) in the type AbstractButton is not applicable for the
arguments (void, void)"

Can you explain what the problem with the code is?

Please edit your post and wrap your code with code tags:
[code=java]
YOUR CODE HERE
[/code]
to get highlighting and preserve formatting.

The method addActionListener(ActionListener) in the type AbstractButton is not applicable for the arguments (void, void)"

You need to read the API doc for that method and see what arguments it takes and then write the code to use the arguments as described in the doc.
