What is the polymorphic feature where constructors and methods are named the same but operate on different input parameters?

• A. Overriding Methods
• B. Polymorphism
• C. Encapsulation
• D. Overloading Methods

Answer: (D)

Overloading is when you have multiple methods or constructors that share the same name but differ in their input parameters. This lets you use the same operation name for different kinds of inputs, and the compiler chooses the right version based on the arguments you pass (their number and types) at compile time. Think of a class that has a constructor taking a single integer and another constructor taking two integers; both have the same class name but are distinguished by their parameter lists. This ability to provide multiple ways to call the same function name is a form of static polymorphism.

Overriding is a different concept: it involves redefining a method in a subclass with the same signature to change behavior at runtime. Encapsulation is about bundling data with the methods that operate on it and restricting access. So the described feature specifically points to overloading.
