QN028. Write a program to print smallest number of array elements.

---

1. Objective

To print smallest number of array elements.

2. Theory

In this program, we use nested loop and if statement. To find the smallest element we arrange all the array elements in ascending order and access index zero element. Which is required output.

3. Source Code

public class Qn028{
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("Smallest elements is: " + arrayVar[0]);
}
}


4. Output

Smallest element is: 6

5. Conclusion

In this way, I would like to conclude that, we can find the smallest array element in array using descending order or ascending order and accessing array index.
