What are some common errors with generics in Java?

What are some common errors with generics in Java?

Common errors include type erasure issues, raw types usage, and incorrect bounds in type parameters.

Can you explain type erasure and how it affects generics?

Type erasure removes generic type information at runtime, which can lead to ClassCastException if not handled properly.

What are raw types and why should I avoid them?

Raw types are non-generic versions of parameterized types. They can lead to unsafe operations and loss of type safety.

How can I fix a ClassCastException related to generics?

Ensure that you're using the correct generic types and avoid casting raw types. Use parameterized types instead.
