Challenge Problems

Push your limits with challenges.

Question 1

Create a generic class Pair<K, V> that can store two different types, K and V. Implement and explain how you would use this class in a program.

💡 Hint: Consider what types can represent key and value in real scenarios.

Question 2

Discuss how you'd implement generic constraints in a data processing application where you only want to process classes that extend a certain interface.

💡 Hint: Think about designing a method responsible for processing data where specific methods must be available.
