New to Java

Hello! I am in need of some help, I have created an application that returns data called by another class in the same package; the idea is that when the user clicks on the "submit" button, a connection class is called that contains the connection information as well as a SQL query that is specific to the application. when I test my application and click the "submit" button, I get the following error:

Exception in thread "AWT-EventQueue-0" java.lang.Error: Unresolved compilation problem:
The type PandoraUI must implement the inherited abstract method ActionListener.actionPerformed(ActionEvent)

I'm not sure what is wrong, if I implement the abstract method, then it seems like nothing happens when I click "Submit"
please any thoughts or ideas would be greatly appreciated!
