Challenge Problems

Push your limits with challenges.

Question 1

Create a generic class to represent a container for items of any type. Discuss how type erasure would affect its methods and how you'd ensure type safety.

💡 Hint: Think about how to constrain types using bounds while implementing the methods.

Question 2

Examine a given piece of legacy code that uses non-generic data types. Propose how to refactor it to use generics while considering type erasure implications.

💡 Hint: Consider existing type assumptions and how they might change with generics.
