Java solution - passes 100% of test cases

From my HackerRank solutions.

I use isProbablePrime() with certainty = 10 to achieve 99.9% accuracy. However, even certainty = 1 (which achieves 50% accuracy) is enough to pass the test cases.

This function is always 100% certain if it tells you if a number is "not prime". If it says "prime", it's only 99.9% certain. It may be the case that it just hasn't found a prime number number that divides the BigInteger yet.

import java.util.Scanner;
import java.math.BigInteger;

public class Solution {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        BigInteger n = scan.nextBigInteger();
        scan.close();
        System.out.println(n.isProbablePrime(10) ? "prime" : "not prime");
    }
}

Let me know if you have any questions.
