HashMap collisions confused me for a long time… until I finally understood chaining and open addressing. HashMaps felt confusing… until I understood how they actually work inside. Today, I went deeper into HashMaps and HashTables, not just using them—but understanding what happens behind the scenes. Here’s what I learned Core concepts I explored 🔸 How HashMaps work internally (hashing, indexing, storing data) 🔸Difference between HashMap and HashTable in Java 🔸How data is stored using key-value pairs techniques I understood 🔸Chaining – handling collisions using linked lists 🔸Open Addressing – finding empty space when collision happens 🔸Why collisions happen and how they are managed Practical learning 🔸Learned HashMap implementation in Java step by step 🔸Understood how real-world applications use hashing for fast access 🔸Improved my problem-solving thinking with data structures I understood the logic behind how HashMaps work internally. Thanks to Kunal Kushwaha for the clear explanation Excited to go deeper into DSA and system-level thinking #Java #DSA #HashMap #HashTable #DataStructures #LearningInPublic #StudentDeveloper #CodingJourney #ProblemSolving #SoftwareEngineering #BuildInPublic
