shotTitle: Find Nth Fibonacci Number

description: This code takes the value of N from user and displays the Nth number of the Fibonacci Series.

N is a variable which inputs a integer value using System.in.

To understand this example, you should have the knowledge of the following Java programming topics:

- [Java Operators](/docs/operators)

- [Java Basic Input and Output](/docs/basic-input-output)

- [Java `for` Loop](/docs/for-loop)

A java program to find the Nth Fibonacci number.

import java.util.Scanner;

public class Fibonacci {

public static void main(String[] args) {

long n, term1=0, term2=1, i, fib=1 ;

Scanner sc = new Scanner(System.in) ;

System.out.print("Enter the value of n: ") ;

n = sc.nextInt() ;

if (n == 1) {

fib = term1;

}

else if (n == 2) {

fib = term2;

}

else {

for (i = 3 ; i <= n ; i ++)

{

fib = term1 + term2;

term1 = term2;

term2 = fib;

}

}

System.out.println("The Nth Fibonacci Number is " + fib) ;

sc.close();

}
