💡 What’s the difference between Comparable and Comparator in Java?
🧩 Both are used to sort objects, but they serve different purposes:
📌 Comparable
➡️ Interface used to define the natural ordering of objects.
➡️ You implement it in the class itself by overriding the compareTo() method.
🔸 Example: String, Integer classes implement Comparable.
📌 Comparator
➡️ Allows you to define custom orderings, outside the class.
➡️ Useful when you want multiple sorting strategies.
🔸 Example: Sort Employee by name or by salary using different comparators.
🧠 Summary:
Comparable = self-sorting (inside the class)
Comparator = external sorting logic
