What are abstract methods in Java?
An example of an AI chatbot conversation about Java abstract methods and their usage.
What are abstract methods in Java?
Abstract methods in Java are methods that are declared without an implementation. They must be implemented by subclasses.
Can you give me an example of an abstract method?
Sure! Here's an example:
abstract class Animal {
abstract void makeSound();
}
In this example, makeSound is an abstract method.
Why would I use abstract methods instead of regular methods?
Abstract methods allow you to define a method signature in a base class while enforcing that subclasses provide their own implementation, promoting a consistent interface.
Can an abstract class have non-abstract methods?
Yes, an abstract class can have both abstract and non-abstract methods. The non-abstract methods can provide default behavior.
