Ekta Agrawal on Instagram: "How does HashMap work internally? 🤯👇 Most asked Java Interview Question !! Stop memorizing theory! Visualize it. 🧠 Here is the step-by-step logic: 1️⃣ The Structure: It’s just an Array of "Buckets". 2️⃣ Hashing: hashCode() converts your Key into an Index (0-15). 3️⃣ The Collision: If two keys get the same index, they form a Linked List chain. 🔗 4️⃣ The Optimization: In Java 8+, if the chain gets too long (>8), it transforms into a Red-Black Tree for faster speed!
