A listener class can be declared as an anonymous inner class. This is a common practice in Java programming. An anonymous inner class is a class without a name, which is defined and instantiated in a single expression. It is often used when the class being created is used just once, so it is not necessary to give it a name. This makes the code more concise and readable.
