Integer arr[] = new Integer[]{1, 4, 17, 7, 25, 3, 100};
int k = 2;
System.out.println("Original Array: ");
System.out.println(Arrays.toString(arr));
System.out.println("K'th smallest element of the said array: ");
Arrays.sort(arr);
System.out.print(arr[k-1] + " ");
System.out.println("\nK'th largest element of the said array:");
Arrays.sort(arr, Collections.reverseOrder());
System.out.print(arr[k-1] + " ");
}
