☕ Java Generics
Generics in Java let you write flexible, type-safe code that works with different types while avoiding casting and runtime errors.
📦 Why Use Generics?
- Type safety: Catch errors at compile-time.
- Code reusability: Write generic algorithms.
- No need for casting: Cleaner, safer code.
