Java program to sort an array of integers using the `Arrays.sort()` method:
import java.util.Arrays;
public class ArraySorting {
public static void main(String[] args) {
// Initialize an array of integers
int[] numbers = {5, 2, 9, 1, 7};
// Print the original array
System.out.println("Original array: " + Arrays.toString(numbers));
// Sort the array in ascending order
Arrays.sort(numbers);
// Print the sorted array
System.out.println("Sorted array: " + Arrays.toString(numbers));
}
}
This program sorts the array `numbers` using the `Arrays.sort()` method, which sorts the array in ascending order by default. The sorted array is then printed to the console.
