Overloading: Distinguish by Argument Count

Easy

Problem Description

Overloading: Distinguish by Argument Count

In this problem, you will create a program that defines two overloaded add methods—one accepting 2 arguments and one accepting 3 arguments—and displays the sum of each call to standard output.

Learning Objective: Understand overloaded methods with different argument counts

Define two add methods with the same name but different argument counts (2 and 3). Java automatically selects which method to call based on argument count.

Input

Line 1: First number (integer)
Line 2: Second number (integer)
Line 3: Third number (integer)

Output

Two args: [first+second]
Three args: [first+second+third]
