Comment your answer 👇 Answer:B Explanation:Map<Integer, String> map = new HashMap<>(); → Creates an empty HashMap map.put(1, "A"); → Map becomes {1=A} map.put(1, "B"); → Same key 1 again → HashMap does not allow duplicate keys → It replaces the old value Now map becomes {1=B} System.out.print(map); → Prints {1=B} ✅ Final Output: {1=B} Simple rule: HashMap allows duplicate values, but not duplicate keys 🔥 #javainterview #corejava #techreels #codingreels #feedexplore

Day-12 of Java interview Concepts Why is HashMap capacity always a power of 2? 🤔 Java uses a bitwise AND operation to calculate the bucket index: index = hash & (capacity - 1) When the capacity is a power of 2, this operation becomes faster and distributes keys uniformly across buckets. That’s why HashMap sizes grow like 16 → 32 → 64 → 128 instead of random numbers. Hashtags: #java #corejava #hashmap #codinginterview #programming @code.apti
