What are some examples of using wildcards in Java?
An example of an AI chatbot conversation about using wildcards in Java programming.
Can you explain what wildcards are in Java?
Sure! Wildcards in Java are used in generics to represent an unknown type. They allow for more flexible code.
What are the different types of wildcards?
There are three types: unbounded wildcards (?), upper-bounded wildcards (? extends T), and lower-bounded wildcards (? super T).
Can you give me an example of using an upper-bounded wildcard?
Absolutely! For instance, if you have a method that accepts a List<? extends Number>, it can take a List of Integer or Double.
How about a lower-bounded wildcard example?
Sure! A method that accepts List<? super Integer> can take a List of Integer or any of its superclasses, like Number.
