Pictorial Presentation:

Java Basic Exercises: Find the kth smallest and largest element in a specified array.

Sample Solution:

Java Code:

import java.util.*;
public class Solution {
  public static void main(String[] args) 
    {
        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] + " ");
	}
}

Sample Output:

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