Method Overloading Concept: Calculator Class

In this problem: You will define three add() methods with different parameters (add(int,int), add(double,double), add(int,int,int)) in a Calculator class to demonstrate how the compiler selects the correct method based on arguments.

Learning Objective: Understand method overloading and learn how the compiler resolves method calls by argument types

Overview

Define three add() methods in the Calculator class:

• add(int a, int b): Returns the sum of two integers
• add(double a, double b): Returns the sum of two doubles
• add(int a, int b, int c): Returns the sum of three integers

Specifications

• Each method returns the calculated result (return types: int, double, int respectively)
• In Main class, call each method and display results
• Double results display in Java's default format

Output Format

add(3, 5) = 8
add(2.5, 3.7) = 6.2
add(1, 2, 3) = 6
