HEEver wondered why ArrayList needs a parameterised constructor? 🤔
In this reel, I explain parameterised constructors in Java using a real-world context of the `ArrayList` class**.
You’ll understand:
* What a parameterised constructor is
* Why `ArrayList(int initialCapacity)` exists
* How passing capacity improves performance
* When and why Java internally uses constructors
If constructors always confused you, this example will make it crystal clear with logic, not mugging**.
📌 Perfect for:
* Java beginners
* Interview preparation
* Understanding Java Collections internally
