Area Calculation with Overloading

In this problem, you will create a program that defines three overloaded calcArea methods with different parameter types and counts to calculate the areas of a square, rectangle, and circle using values read from standard input, and displays the results.

Learning Objective: Practice method overloading by varying both the number and types of parameters

Overview

Define three methods all named calcArea to calculate the area of a square, rectangle, and circle using Scanner input.

Specifications

1. calcArea(int side): returns the area of a square (side * side)
2. calcArea(int width, int height): returns the area of a rectangle (width * height)
3. calcArea(double radius): returns the area of a circle (Math.PI * radius * radius) rounded to 2 decimal places
4. Call each method from main and output the results with labels

Input Format

side
width
height
radius

Output Format

Square: <square area>
Rectangle: <rectangle area>
Circle: <circle area (2 decimal places)>

Sample Input/Output
