+title: Java program To Find The Nth Fibonacci Number
+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)

+## To find the Nth Fibonacci number
+
+A java program to find the Nth Fibonacci number.
+
+
+## Java Code
+
+```java
+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();
+    }
+}
+```
+
+#### Output 1
+
+```plaintext
+Enter the value of n: 69
+The Nth Fibonacci Number is 72723460248141
+```
+
+#### Output 2
+
+```plaintext
+Enter the value of n: 12
+The Nth Fibonacci Number is 89
+```
