# Java: Find the kth smallest and largest element in a specified array

## Java Basic: Exercise-161 with Solution

Write a Java program to find the kth smallest and largest element in a given array. Elements in the array can be in any order.

**Visual Presentation:**

**Sample Solution:**

**Java Code:**

```
import java.util.*;
public class Solution {
public static void main(String[] args) {
// Initializing an array of integers
Integer arr[] = new Integer[]{1, 4, 17, 7, 25, 3, 100};
int k = 2; // Initializing the value of 'k' as 2
// Displaying the original array
System.out.println("Original Array: ");
System.out.println(Arrays.toString(arr));
// Displaying the k'th smallest element of the array
System.out.println("K'th smallest element of the said array: ");
// Sorting the array in ascending order
Arrays.sort(arr);
// Printing the k'th smallest element from the sorted array
System.out.print(arr[k-1] + " ");
// Displaying the k'th largest element of the array
System.out.println("\nK'th largest element of the said array:");
// Sorting the array in descending order to find the k'th largest element
Arrays.sort(arr, Collections.reverseOrder());
// Printing the k'th largest element from the sorted array
System.out.print(arr[k-1] + " ");
}
}
```

Sample Output:

Original Array: [1, 4, 17, 7, 25, 3, 100] K'th smallest element of the said array: 3 K'th largest element of the said array: 25
