The code `Arrays.sort(nums);` sorts the array `nums` in ascending order....

The code Arrays.sort(nums); sorts the array nums in ascending order. Here's a breakdown of what it does:

• Arrays: This is a utility class in Java that provides methods for manipulating arrays, such as sorting and searching.
• sort(nums): The sort method organizes the elements of the provided array nums in natural, ascending order (from smallest to largest for primitive types like integers or any objects that implement Comparable).

Key Points:

1. If nums is an array of primitives (e.g., int[] or double[]):
   • The elements are sorted in ascending numeric order.
2. If nums is an array of objects (e.g., String[] or custom objects):
   • The elements are sorted based on their "natural order" (defined in the compareTo method of the Comparable interface or with a provided Comparator).

For example:

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int[] nums = {5, 3, 8, 1, 9};
        Arrays.sort(nums);  // Sorts the array in ascending order
        System.out.println(Arrays.toString(nums));  // Prints: [1, 3, 5, 8, 9]
    }
}

The array nums is modified in-place and will now be sorted in ascending order after the call to Arrays.sort().
