Implement Area Calculation Methods with Overloading

In this problem, you will create a program that reads four values from standard input — a square's side length, a rectangle's width and height, and a circle's radius — then implements three overloaded methods: calculateArea(int side) for a square, calculateArea(int width, int height) for a rectangle, and calculateArea(double radius) for a circle.

Input:

• Line 1: side (int) — side length of the square
• Line 2: width (int) — width of the rectangle
• Line 3: height (int) — height of the rectangle
• Line 4: radius (double) — radius of the circle

Output:

Square: <square_area>
Rectangle: <rectangle_area>
Circle: <circle_area (2 decimal places)>

Learning Objectives:

• Understand how method overloading works
• See how the compiler selects the correct method based on argument type and count
• Design a clean API by giving a unified name to related operations
