What are some common mistakes when using generics in Java?

Some common mistakes include using raw types, not understanding type erasure, and failing to use bounded type parameters.

Can you explain why using raw types is a mistake?

Using raw types bypasses the type safety that generics provide, leading to potential ClassCastExceptions at runtime.

What is type erasure?

Type erasure is the process by which the Java compiler removes all generic type information during compilation, which can lead to unexpected behavior.

How can I avoid these mistakes?

To avoid these mistakes, always use parameterized types, understand the implications of type erasure, and utilize bounded types when necessary.
