Fibonacci Series in Java

As we have talked earlier about it, the Fibonacci series starts with 0 and 1. And the next number is always the sum of the previous two numbers. For example: In this series  0,1,1,2,3,5,8,13,21,34,55,............ You can see that after o and 1, every digit is the sum of the previous two digits. Just like 0+1= 1, 1+1=2, 2+1=3, 3+2=5, 5+3=8, and so on. 

I think we have already answered this above. We have mainly two methods to code for the Fibonacci series. One with the help of loops and the other with the help of recursion. As we have already discussed the for loop example, let’s now look into a recursion code for the Fibonacci series.

class FibExp{ 

static int a1=0,a2=1,a3=0; 

static void printFibonacci(int count) 

{ 

if(count>0){ 

a3 = a1 + a2; 

a1 = a2; 

a2 = a3; 

System.out.print(" "+a3); 

printFibonacci(count-1);
 

} 

} 

public static void main(String args[]){ 

int count=9; 

System.out.print(a1+" "+a2); 

printFibonacci(count-2);/ } 

}

The output of the following code is: 

0 1 1 2 3 5
