Difference Between override and Overload

In this problem, you will create a program that implements method overloading in the Calculator class and method overriding through inheritance in the AdvancedCalculator class, reads values from Scanner, and displays the result of each method call to standard output.

Learning Objective: Understand the difference between method override and overload

Overview

Create a program that implements both overloading within a class and overriding through inheritance, using input values to verify the behavior.

Specifications

• Define add(int, int) method in Calculator class
• Overload with add(double, double) in same class
• AdvancedCalculator extends Calculator and overrides add(int, int) (adds 5 to result)
• Main reads values from standard input and tests all methods

Input Format

Read the following values from standard input, one per line:

1. Integer a (first argument for int add)
2. Integer b (second argument for int add)
3. Double c (first argument for double add)
4. Double d (second argument for double add)
5. Integer e (first argument for AdvancedCalculator add)
6. Integer f (second argument for AdvancedCalculator add)

Output Format

Int add: [result of a+b]
Double add: [result of c+d]
Advanced add: [result of e+f+5]
