How to iteratively find Fibonacci for integer values in Java

public class Fibonacci {
	private static int fib(int n) {
		int prevprev = 0, prev = 1;
		int current = n;
		for (int i = 2; i <= n; i++) {
			current = prevprev + prev;
			prevprev = prev;
			prev = current;
		}
		return current;
	}
	
	public static void main(String[] args) {
		System.out.println(fib(3)); // 2
		System.out.println(fib(6)); // 8
	}

}
