QN029. Write a program to print second smallest number of array elements.

---

1. Objective

To print second smallest number of array elements.

2. Theory

In this program we use nested loop and if statement. To find the second smallest element we arrange elements in ascending order and accessing index 1.

3. Source Code

public class Qn029{
public static void main(String[] args){
int arrayVar[] = {12, 6, 17, 9};
for(int i = 0; i<4; i++)
{
for(int j = i+1; j<4; j++)
{
if(arrayVar[i] > arrayVar[j])
{
int temp = arrayVar[i];
arrayVar[i] = arrayVar[j];
arrayVar[j] = temp;
}
}
}
System.out.println("Second smallest number is: " + arrayVar[1]);
}
}


4. Output

Second smallest number is: 9

5. Conclusion

In this way, I would like to conclude that, using this technique we can find the second smallest array element.
