An example of an AI chatbot conversation about type erasure in Java.
What is type erasure in Java?
Type erasure is a process in Java where generic type information is removed during compilation, allowing for backward compatibility.
Can you give me an example of type erasure?
Sure! For instance, if you have a generic class like List<T>, at runtime, it becomes just List without any type information.
How does type erasure affect performance?
Type erasure can lead to performance overhead due to the need for casting and potential runtime exceptions, but it ensures compatibility.
Are there any alternatives to type erasure?
Yes, some languages use reified generics, which retain type information at runtime, but Java chose type erasure for its design.
