Constructor Chaining in Java: Implicit and Explicit Calls Explained
Constructor Chaining in Java Constructor chaining is a mechanism in Java where one constructor calls another constructor, usually from the parent (super) class, during object creation. This process ensures that all parent class constructors are executed before child class constructors, maintaining proper object initialization. ✅ Key Requirements Constructor chaining requires inheritance It is performed using the super() statement It cannot be performed within the same class using super() The super() call must be the first statement in the constructor 🌍 Real-Life Example Building Construction First, foundation is built (Parent class constructor) Then walls and rooms are built (Child class constructor) Similarly, Java first executes the superclass constructor, then the subclass constructor. 🔹 Types of Constructor Chaining Constructor chaining can be performed in two ways: Implicit Constructor Call Explicit Constructor Call 1.
