Why we even use constructors in Java if we can use methods?

4,483 PointsWe use constructors to create objects. We use methods to change an object after it is created. So that's why we need a constructor. You cannot "construct" an object with a method. You can only use a method to change the object after it is created. (Every class has a default constructor whether you define one explicitly or not.)
To put this in code, when you create a new Car object as shown via new Car()
, "Car()" refers to the constructor and cannot be replaced by a method.
