Write a Java Program To Print Fibonacci Series In Java

Fibonacci series in Java

In fibonacci series, next number is the sum of previous two numbers for example 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 etc. The first two numbers of fibonacci series are 0 and 1.

There are two ways to write the fibonacci series program in java:

• Fibonacci Series without using recursion
• Fibonacci Series using recursion

package com.java2novice.algos;

public class MyFibonacci {

    public static void main(String a[]){

         

         int febCount = 15;

         int[] feb = new int[febCount];

         feb[0] = 0;

         feb[1] = 1;

         for(int i=2; i < febCount; i++){

             feb[i] = feb[i-1] + feb[i-2];

         }

         for(int i=0; i< febCount; i++){

                 System.out.print(feb[i] + " ");

         }

    }

}

                                                OR

1.    class FibonacciExample1{  

2.    public static void main(String args[])  

3.    {    

4.     int n1=0,n2=1,n3,i,count=10;    

5.     System.out.print(n1+" "+n2);//printing 0 and 1    

6.        

7.     for(i=2;i<count;++i)//loop starts from 2 because 0 and 1 are already printed    

8.     {    

9.      n3=n1+n2;    

10.   System.out.print(" "+n3);    

11.   n1=n2;    

12.   n2=n3;    

13.  }    

14.   

15. }}
