Decoding Java's Random Class

Report a typo

Consider the following code snippet in Java. What is true about the output of the program?


import java.util.Random;

public class Test {
    public static void main(String[] args) {
        Random rand = new Random();
        int randomNum = rand.nextInt(50);
        System.out.println(randomNum);
    }
}

Select one option from the list

The program will output a random number between 0 and 49, inclusive.

The program will not compile because the Random class does not exist.

The program will always output the same number every time it runs.

The nextInt(50) method call will throw an exception because an argument is provided.

The program will output a number from the set {0, 1, 2, ..., 49, 50}.
