Java ExecutionException Error

[feral marlin]

I don't really understand this error nor do I know what I'm doing wrong.

import java.util.Random;

public class RandomTester {
    private final Random random;

    public RandomTester() {
        random = new Random();
    }

    /**
     * Print a single random integer using System.out.println.
     */
    public void printOneRandom() {
        System.out.println(random.nextInt(100));
    }

    public static void main(String[] args) {
        RandomTester randomTester = new RandomTester();
        randomTester.printOneRandom();
    }
}

here's more info on the errors:

My best guest is that jetbrains is responsible for this error as when the location of the error is given it's in the jetbrains package, maybe copy the error and search for fixes
