Write a program to generate Fibonacci Numbers

April 23, 2010

Fibonacci Series in JavaIn mathematics, the Fibonacci numbers are the numbers in the following sequence:


By definition, the first two Fibonacci numbers are 0 and 1, and each remaining number is the sum of the previous two. Some sources omit the initial 0, instead beginning the sequence with two 1s.

In mathematical terms, the sequence Fn of Fibonacci numbers is defined by the recurrence relation

    F_n = F_{n-1} + F_{n-2} with seed values

F_0 = 0 and F_1 = 1.

The following flowchart illustrates how to generate Fibonacci Series for the first N numbers.

Fibonacci Generator Program

The following program shows how to generate the Fibonacci Series in Java. It uses recursion to compute the next Fibonacci number.


Program Output

Generate Fibonacci up to : 10
Fib No : 1 is 0
Fib No : 2 is 1
Fib No : 3 is 1
Fib No : 4 is 2
Fib No : 5 is 3
Fib No : 6 is 5
Fib No : 7 is 8
Fib No : 8 is 13
Fib No : 9 is 21
Fib No : 10 is 34
