In this java program, we are reading an integer array of N elements and finding second smallest element among them. By Chandra Shekhar Last updated : December 23, 2023

## Problem statement

Given an array of N integers and we have to find its second minimum/smallest element using Java program.

### Example

```Input:
Enter number of elements: 4
Input elements: 45, 25, 69, 40

Output:
Second smallest element in: 40
```

## Program to find second smallest element from an array in java

```import java.util.Scanner;

public class ExArrayFindSecondSmallest {
public static void main(String[] args) {
// Intialising the variables
int n, min;
Scanner Sc = new Scanner(System.in);

// Enter the number of elements.
System.out.print("Enter number of elements : ");
n = Sc.nextInt();

// creating an array.
int a[] = new int[n];

// enter array elements.
System.out.println("Enter the elements in array : ");
for (int i = 0; i < n; i++) {
a[i] = Sc.nextInt();
}

for (int i = 0; i < n; i++) {
for (int j = i + 1; j < n; j++) {
if (a[i] > a[j]) {
min = a[i];
a[i] = a[j];
a[j] = min;
}
}
}
System.out.println("The Smallest element in the array is :" + a[1]);
}
}
```

### Output

```Enter number of elements : 4
Enter the elements in array :
45
25
69
40
The Smallest element in the array is :40
```
