Method Overloading: Addition Methods

In this problem, you will create a program that defines two add methods with the same name but different numbers of parameters in the Calculator class, reads values from standard input, and prints the computed sums.

Learning Objective: Understand how to define multiple methods with the same name but different parameter types or counts

Overview

Define two add methods in the Calculator class. One receives two int arguments, the other receives three int arguments. Both return the sum as a return value. In the Main class, read numbers from standard input and call each add method.

Specifications

• Define the following two add methods in the Calculator class
  • public int add(int a, int b) - return sum of two numbers
  • public int add(int a, int b, int c) - return sum of three numbers
• In Main, read input values using Scanner and print the results of calling both overloads

Input Format

Line 1: a b (two integers for the 2-argument add, space-separated)
Line 2: a b c (three integers for the 3-argument add, space-separated)

Output Format

Line 1: result of add(a, b)
Line 2: result of add(a, b, c)

Examples

Input:
10 20
10 20 30

Output:
30
60
