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 = 3;
  System.out.println("Original Array: ");
  System.out.println(Arrays.toString(arr));
  System.out.println(k + " smallest elements of the said array are:");
  Arrays.sort(arr);
  for (int i = 0; i < k; i++)
   System.out.print(arr[i] + " ");
 }
}

Sample Output:

Original Array: 
[1, 4, 17, 7, 25, 3, 100]
3 smallest elements of the said array are:
