An example of an AI chatbot conversation about advanced concepts in Java Generics.
What are some advanced topics in Java Generics?
Advanced topics in Java Generics include wildcards, bounded type parameters, and type erasure. Would you like to explore any specific topic?
Can you explain wildcards in Java Generics?
Sure! Wildcards in Java Generics allow you to use a placeholder for a type. They are represented by the question mark (?) and can be unbounded, bounded above, or bounded below.
What is the difference between bounded and unbounded wildcards?
Unbounded wildcards allow any type, while bounded wildcards restrict the types to a specific range. For example, <? extends T> allows any subtype of T.
How does type erasure work in Java Generics?
Type erasure removes all generic type information during compilation, replacing it with the bounds or Object if no bounds are specified. This ensures compatibility with legacy code.
