# Java Average Of Array

Hey guys!! Welcome to flower brackets blog. In the following post you will learn java average of array.

Here I am going to show you how to find the average of an array in java of predefined array elements. So, let us get into program to find the average of numbers using array,

```public class AverageArrayDemo
{
public static void main(String[] args)
{
double num[] = {30,12.5,14,24.56,19,89.45,128};
double total = 0;

for(int a = 0; a < num.length; a++)
{
total = total + num[a];
}

double average = total / num.length;
System.out.println("Average is : " + average);
}
}

```

Output:

Average is : 45.35857142857143

#### Java program to calculate average using array

Here we are going to learn how to calculate average of array input. For this we are using Scanner class to get all the numbers from user,

```import java.util.Scanner;

public class AverageArrayExample
{
public static void main(String[] args)
{
System.out.println("Please enter the numbers you want to find average : ");
Scanner sc = new Scanner(System.in);
int num = sc.nextInt();
double arrAverage[] = new double[num];
double sum = 0;

for(int a = 0; a < arrAverage.length; a++)
{
System.out.print("Please enter no." + (a + 1) + " : ");
arrAverage[a] = sc.nextDouble();
}

for(int a = 0; a < arrAverage.length; a++)
{
sum = sum + arrAverage[a];
}
double average = sum / arrAverage.length;
System.out.format("The average of array is : %.2f", average);
sc.close();
}
}

```

Output:

```Please enter the numbers you want to find average : 5
The average of array is : 54.84

```
