# 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.

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
```
