🟢Learning Java? Well it's not just critical not know how to use polymorphism and constructor but the difference between constructor and polymorphism. Find out how to take your Java skills a notch higher, here.
Dive into the world of Java programming with our in-depth tutorial on Polymorphism and Constructors, presented by upGrad. This comprehensive guide will help you understand these fundamental concepts, enabling you to write more efficient and flexible Java code.

*Introduction to Polymorphism:*
Start by grasping the concept of polymorphism in Java. Polymorphism, a core principle of object-oriented programming (OOP), allows objects to be treated as instances of their parent class rather than their actual class. This flexibility is key for creating scalable and maintainable code.

*Types of Polymorphism:*
Understand the two main types of polymorphism in Java:
- *Compile-time Polymorphism:* Learn how Java allows multiple methods with the same name but different parameters within a class. This technique is used to increase the readability of the program.
- *Method Overloading:* Explore how to define multiple methods with the same name but different parameter lists. Understand the benefits of overloading for code clarity and reusability.
- *Operator Overloading:* Although not supported in Java like in some other languages, understand how Java handles basic operator overloading internally for primitives and built-in types.
- *Runtime Polymorphism:* Discover how a subclass can provide a specific implementation of a method that is already defined in its superclass. This is essential for dynamic method resolution during runtime.
- *Method Overriding:* Learn how to override methods in subclasses to provide specific behavior while maintaining a common interface.

*Introduction to Constructors:*
Next, delve into the role of constructors in Java. Constructors are special methods used to initialize objects. Understand their importance and how they differ from regular methods.
- *Default Constructor:* Learn about the default constructor provided by Java if no constructors are explicitly defined.
- *Parameterized Constructor:* Understand how to create parameterized constructors to initialize objects with specific values.

*Combining Polymorphism and Constructors:*
Discover how constructors and polymorphism work together in Java:
- *Constructor Overloading:* Learn how to overload constructors to create objects in different ways.
- *Chaining Constructors:* Explore constructor chaining using the `this()` and `super()` keywords to call constructors within the same class or parent class.
