Method Overriding: Shape Area Calculator

In this problem, you will create a program that overrides the getArea() method in Circle and Rectangle subclasses of Shape to calculate each shape's area using values read from standard input and display the results.

Learning Objective: Override methods with return values

Create a Shape class representing shapes and Circle/Rectangle classes inheriting from it. Override the getArea() method to implement each shape's area calculation formula.

Input

radius (double)
width (double)
height (double)

Output

Circle area: <area (2 decimal places)>
Rectangle area: <area (2 decimal places)>

Examples

Example 1: radius=5, width=4, height=6

Input:

5.0
4.0
6.0

Output:

Circle area: 78.54
Rectangle area: 24.00

Example 2: radius=3, width=5, height=8

Input:

3.0
5.0
8.0

Output:

Circle area: 28.27
Rectangle area: 40.00

Formulas

• Circle area: π × radius² (use Math.PI)
• Rectangle area: width × height
