Problem Statement
What are the main collection interfaces in Kotlin?
Explanation
Kotlin provides three main collection interfaces: List for ordered collections allowing duplicates, Set for unordered collections with unique elements, and Map for key-value pairs. Each interface has both read-only versions like List, Set, Map and mutable versions like MutableList, MutableSet, MutableMap.
Read-only collections don't have methods to add or remove elements, promoting immutability and safer code, though the underlying implementation might still be mutable. Mutable collections provide methods like add, remove, and clear for modifying the collection.
This separation between read-only and mutable interfaces is a key Kotlin feature not present in Java, helping prevent accidental modifications and making code intent clearer.
