What is contravariance in Java?
An example of an AI chatbot conversation about contravariance in Java.
Can you explain what contravariance is in Java?
Sure! Contravariance is a concept in Java generics that allows a method to accept arguments of a more general type than specified.
Can you give me an example of contravariance in action?
Absolutely! If you have a method that takes a List<Animal>, you can pass a List<Dog> to it because Dog is a subtype of Animal.
How does this differ from covariance?
Covariance allows you to use a more specific type when returning values, while contravariance allows for more general types in method parameters.
