Why is it important that Kotlin does not expose primitive types at the source level from a language design perspective?
AIt allows Kotlin to provide null safety and uniform type handling
BIt forces developers to manage memory manually
CIt limits Kotlin to only work on JVM
DIt prevents Kotlin from supporting generics
Step-by-Step Solution
Solution:

  1. Step 1: Consider Kotlin's goals for safety and simplicity

    Hiding primitives helps Kotlin enforce null safety and treat all types uniformly.

  2. Step 2: Understand design benefits

    This design reduces errors and complexity for developers, improving code quality.

  3. Final Answer:

    It allows Kotlin to provide null safety and uniform type handling -> Option A

  4. Quick Check:

    Design for safety and uniformity [OK]
Quick Trick: Unified types enable null safety and simpler code [OK]
Common Mistakes:
MISTAKES
  • Thinking manual memory management is required
  • Assuming Kotlin only works on JVM due to this
  • Believing generics are unsupported
