Git: Version control system to track code changes. 🌿
Generics: Code templates that work with any data type. 🧰

H

Hashing: Converting data into a fixed-size value for fast lookups. 🔑
Heap: Memory area for dynamic allocation. ⛰️
HTTP: Protocol for communication on the web. 🌐

I

IDE (Integrated Development Environment): Tool with editor, debugger, and compiler. 🧰
Immutable: Data that can’t be changed after creation. 🔒
Interface: Contract defining methods a class must implement. 🤝
