How do generics work in Java?
An example of an AI chatbot conversation about generics in Java programming.
Can you explain how generics work in Java?
Sure! Generics in Java allow you to define classes, interfaces, and methods with a placeholder for types, enabling type safety.
Why should I use generics instead of just using Object?
Using generics provides type safety at compile time, reducing runtime errors and eliminating the need for casting.
Can you give me an example of a generic class?
Absolutely! Here's a simple example: class Box<T> { private T item; public void setItem(T item) { this.item = item; } public T getItem() { return item; } }.
What are some common use cases for generics?
Common use cases include collections like List<T>, Map<K,V>, and creating reusable algorithms that work with different types.
