Generics allow you to write classes, interfaces, and methods that can work with different data types while maintaining type safety.
Example:
List〈String〉 names = new ArrayList〈〉();
Here, List〈String〉 ensures only String objects can be stored.
✅ Advantages of Generics
1️⃣ Type safety – Detect type errors at compile time, not runtime
2️⃣ No casting needed – No need to manually cast objects when retrieving them
3️⃣ Code reusability – Same code works with different types
4️⃣ Better readability – Clear intent of what type is expected
💡 With Generics, you write cleaner, safer, and reusable code.
