Practical case

Calculate the circle Area

public class Circle {

    public static double calculateArea(double radius) {
        return Math.PI * radius * radius;
    }

    public static void main(String[] args) {
        double radius = 5.0;
        double area = calculateArea(radius);
        System.out.println("Area of circle with radius " + radius + ": " + area);
    }
}

Print Fibonacci Sequence

public class Fibonacci {

    public static void main(String[] args) {
        int n = 10;
        for (int i = 0; i < n; i++) {
            System.out.print(calculateFibonacci(i) + " ");
        }
    }

    private static int calculateFibonacci(int n) {
        if (n == 0 || n == 1) {
            return 1;
        }
        return calculateFibonacci(n - 1) + calculateFibonacci(n - 2);
    }
}
