# Java Program to Find Average of Numbers In Array

This below Java Program will find the average of integer elements from Array.

### Java Code To Find the Average value of Number Elements ( Elements will be taken from user inputs) from an array

```import java.util.Scanner;

public class Codespeedy {
public static void main (String[] args) {
Scanner input=new Scanner(System.in);
System.out.println("Enter the size of array:");
int n=input.nextInt();
double total=0;
double array[]=new double[n];
System.out.println("Enter the elements one by one:");
for (int s=0;s<array.length;s++){
array[s]=input.nextDouble();
}
for(int i=0;i<array.length;i++){
total=total+array[i];
}
double average=total/n;
System.out.println("The averag value is:"+average);

}
}```

Output:

```run:
Enter the size of array:
5
Enter the elements one by one:
22.11
55.22
54.28
48.658
15.25
The averag value is:39.10360000000001

```

Merge (Combine) Two or More Arrays Into A Single Array In Java

### Algorithm and Explanation Of This Java Average Value Calculator Program

• Take the size of the array from user input.
• Take the elements one by one from the user using for loop and array index.
• Add each element to the previous element and store it in a variable. (I have initialized the variable total with zero used it)
• After adding all the variables, divide the total value with the number of elements in the array. (total/n)
• Store the result in any variable.
• Print the final result to show the average value to the user.

Remove Duplicate Elements From Unsorted Array And Print Sorted

```for (int s=0;s<array.length;s++){
array[s]=input.nextDouble();
}```

This is the array input part from the user.

```for(int i=0;i<array.length;i++){
total=total+array[i];
}```

This is the main algorithm of our program to add the elements of our array

```double average=total/n;
System.out.println("The averag value is:"+average);```

This is for output statement.
