How to find nTh number of Fibonacci series

import java.util.Scanner;

public class NthFibonacci {

	public static void main(String[] args) {

		Scanner number=new Scanner(System.in);
		// To find the nTh number of Fibonacci series, read nTh value here.
		System.out.println("Enter nTh number=");
		int nTh=number.nextInt();
		number.close();

		//Call the function nthFib() with nth value as parameter
		System.out.println("The "+nTh+"th value of the Fibonacci series is "+ NthFib(nTh));
	}

	private static int NthFib(int nthNum) {

		int[] fib=new int[nthNum];	
		//Initialize the first two values in the Fibonacci series
		fib[0]=0;
		fib[1]=1;

		//Evaluate each term in the series until the nthNum
		for(int i=2;i<nthNum;i++) 
			fib[i]=fib[i-1]+fib[i-2];
		return fib[nthNum-1];
	}
