Answer:

Java Program to find Second Smallest Number in an Array

public class SecondSmallestInArrayExample{

public static int getSecondSmallest(int[] a, int total){

int temp;

for (int i = 0; i < total; i++)

{

for (int j = i + 1; j < total; j++)

{

if (a[i] > a[j])

Answer:

Java Program to find Second Smallest Number in an Array

We can find the second smallest number in an array in java by sorting the array and returning the 2nd element. Let's see the full example to find the second smallest number in java array.

public class SecondSmallestInArrayExample{  

public static int getSecondSmallest(int[] a, int total){  

int temp;  

for (int i = 0; i < total; i++)   

        {  

            for (int j = i + 1; j < total; j++)   

            {  

                if (a[i] > a[j])   

                {  

                    temp = a[i];  

                    a[i] = a[j];  

                    a[j] = temp;  

                }  

            }  

        }  

       return a[1];//2nd element because index starts from 0  

}  

public static void main(String args[]){  

int a[]={1,2,5,6,3,2};  

int b[]={44,66,99,77,33,22,55};  

System.out.println("Second smallest: "+getSecondSmallest(a,6));  

System.out.println("Second smallest: "+getSecondSmallest(b,7));
