Java Java Objects Meet Objects Constructors

Why we even use constructors?

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

Besides the fact that you can make multiple objects of that type, change their variable’s values and some other advantages, it also helps making your code more intelligible for a not so trained person, as you declare an object like one in real life.

We 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.

A constructor is used when you create an object. https://docs.oracle.com/javase/tutorial/reflect/member/ctor.html
