Can we override Constructor?

Nope—we can’t override a constructor in Java. Here’s why:

🚫 Why Constructors Can’t Be Overridden

  1. Constructors are not inherited.
    Since constructors belong specifically to the class they’re defined in and don’t get passed down to subclasses, there’s nothing to override.
  2. Their purpose is class-specific.
    They’re used to initialize objects of a particular class, and each class defines its own way of doing that.

🤔 But You Can Do This Instead:

  • Constructor Overloading:
    You can have multiple constructors in the same class with different parameter lists:
class Student {
    Student() {
        System.out.println("Default constructor");
    }

    Student(String name) {
        System.out.println("Student name: " + name);
    }
}
  • Super Constructor Call:
    A subclass can call a superclass constructor using super()—which lets you reuse initialization logic:
class Person {
    Person(String name) {
        System.out.println("Person: " + name);
    }
}

class Employee extends Person {
    Employee(String name) {
        super(name);  // Calls Person's constructor
    }
}

So, you can extend, overload, or invoke a constructor from a parent class—but not override it.
