What is type erasure?
An example of an AI chatbot conversation about type erasure in programming languages.
Can you explain what type erasure is?
Type erasure is a concept in programming where type information is not retained at runtime. It’s commonly seen in languages like Java and TypeScript.
Why is type erasure used in programming?
Type erasure allows for greater flexibility and compatibility, enabling generic programming while keeping the runtime lightweight.
Can you give an example of type erasure in Java?
Sure! In Java, when you use generics, the type parameters are removed during compilation, so at runtime, you only have the raw types.
What are the drawbacks of type erasure?
Drawbacks include the inability to use certain type checks at runtime and potential ClassCastExceptions if not handled properly.
