Array Creation and Access Practice Test

A teacher stores quiz scores in an array of integers. Given the code snippet,

public class Grades {

  public static void main(String[] args) {

    int[] grades = new int<u>5</u>; // 5 students

    grades<u>0</u> = 90;

    grades<u>1</u> = 85;

  }

}

The array stores whole-number scores. How is the array grades initialized in the code?

A store tracks stock counts by product index. Given the code snippet,

public class Inventory {

  public static void main(String[] args) {

    int[] stock = {12, 5, 0, 18}; // index = product ID (0-3)

    int productId = 1;

    int current = stock<u>productId</u>; // retrieve stock for product 1

    System.out.println(current);

  }

}

Array indexing starts at 0. What is the output of accessing element at index 1 in the array?
