Procedure

The four-pointed star can be viewed as a square eclipsed by four circles. Let r be the radius of the circles, or a half of the side of the square. Write a Java program to calculate the area of the four-pointed star.

1. Implement a class with stub methods main, squareArea, circleArea, getRadius, printArea.
2. Implement the main method by calling other methods.
3. Implement the getRadius method to prompt the user to enter a value.
4. Implement the squareArea method to return of the area of a square.
5. Implement the circleArea method to return of the area of a circle.
6. Implement the printArea method to print the area of the four-pointed star.
