How to use method for calculating fibonacci series?
SolutionThis example shows the way of using method for calculating Fibonacci Series upto numbers.
public class MainClass {
public static long fibonacci(long number) {
if ((number == 0) || (number == 1)) return number;
else return fibonacci(number - 1) + fibonacci(number - 2);
}
public static void main(String[] args) {
for (int counter = 0; counter <= 10; counter++){
System.out.printf("Fibonacci of %d is: %d\n", counter, fibonacci(counter));
}
}
}
Result
The above code sample will produce the following result.
Fibonacci of 0 is: 0 Fibonacci of 1 is: 1 Fibonacci of 2 is: 1 Fibonacci of 3 is: 2 Fibonacci of 4 is: 3 Fibonacci of 5 is: 5 Fibonacci of 6 is: 8 Fibonacci of 7 is: 13 Fibonacci of 8 is: 21 Fibonacci of 9 is: 34 Fibonacci of 10 is: 55
The following is an another example of Fibonacci series
public class ExampleFibonacci {
public static void main(String a[]) {
int count = 15;
int[] feb = new int[count];
feb[0] = 0;
feb[1] = 1;
for(int i = 2; i < count; i++) {
feb[i] = feb[i-1] + feb[i-2];
}
for(int i = 0; i < count; i++) {
System.out.print(feb[i] + " ");
}
}
}
The above code sample will produce the following result.
0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
