// Java program to find smallest and second smallest elements
import java.io.*;
class SecondSmallest
{
/* Function to print first smallest and second smallest
elements */
static void print2Smallest(int arr[])
{
int first, second, arr_size = arr.length;
/* There should be atleast two elements */
if (arr_size < 2)
{
System.out.println(" Invalid Input ");
return;
}
first = second = Integer.MAX_VALUE;
for (int i = 0; i < arr_size ; i ++)
{
/* If current element is smaller than first
then update both first and second */
if (arr[i] < first)
{
second = first;
first = arr[i];
}
/* If arr[i] is in between first and second
then update second */
else if (arr[i] < second && arr[i] != first)
second = arr[i];
}
if (second == Integer.MAX_VALUE)
System.out.println("There is no second" +
"smallest element");
else
System.out.println("The smallest element is " +
first + " and second Smallest" +
" element is " + second);
}
/* Driver program to test above functions */
public static void main (String[] args)
{
int arr[] = {12, 13, 1, 10, 34, 1};
print2Smallest(arr);
}
}
