Output:

Explanation:
• In this program, we define a method reverseArray that takes an array of integers as a parameter and reverses
the elements of the array in place.
• We declare an array numbers containing integers in the main method.
• We call the reverseArray method and pass the numbers array as an argument.
• Inside the reverseArray method, we use two pointers (left and right) to traverse the array from both ends and
swap the elements until they meet in the middle.
• After reversing the array, we display the elements of the reversed array in the main method.

TASK 5: Checking if an Array is Sorted in Ascending Order
public class SortedArrayDemo {
public static void main(String[] args) {

int[] numbers = {1, 3, 5, 7, 9};
// Calling the method to check if the array is sorted
boolean sorted = isSorted(numbers);
if (sorted) {
System.out.println(“The array is sorted in ascending order.”);
} else {

System.out.println(“The array is not sorted in ascending order.”);
}
}
// Method to check if an array is sorted in ascending order

public static boolean isSorted(int[] arr) {
for (int i = 0; i < arr.length - 1; i++) {
if (arr[i] > arr[i + 1]) {
return false;
}

}
return true;
}
}
