Learn object-oriented programming concepts like classes, inheritance, and polymorphism in Java to create efficient and reusable code.

Android Development with Java

This module covers all the concepts related to object-oriented programming (OOP). Starting with the basics and reviewing complex topics like inheritance and polymorphism, this module is filled with illustrations, exercises, quizzes, and hands-on challenges. We’ll walk away with an understanding of the classes and the behavior of objects. By the end of this module, we'll be able to write cleaner, more modular, and more reusable code.

## Problem Statement

Implement a method `squareSum(double num1, double num2, double num3)` in a class `SquareSum` which takes three numbers, square them and returns their sum.

### Input:
Three floating point numbers.

### Output:
Sum of the squares of passing numbers

### Sample Input
```C++
2, 3, 4

```

### Sample Output
```C++
29
```
