Hello guys!! Welcome to flower brackets blog. In this post we going to learn how to calculate sum and average of values in an array in java.

Okay, in this program we will use an array and loop to calculate the sum and average of a set of values in java.

So let’s start by declaring the array

#### Example: sum and average of values in an array in java

public class SumAverageDemo { public static void main(String[] args) { double var[] = {2,4,6,8,10}; double sum = 0; for(double value : var) { sum += value; } System.out.println("The sum is : " + sum); double average = 0; if(var.length > 0) { average = sum / var.length; } System.out.println("The average is : " + average); } }

**Output:**

#### Maximum and minimum values in an array in java

Right, this program will show you how to calculate the maximum and minimum values inside of an array.

So I just have array here,

**Maximum:**

public class SumAverageDemo { public static void main(String[] args) { double var[] = {21,40,61,85,100}; double max = var[0]; for(int a = 0; a < var.length; a++) { if(var[a] > max) { max = var[a]; } } System.out.println("The maximum number is : " + max); } }

**Output:**

The maximum number is : 100.0

**Minimum:**

public class SumAverageDemo { public static void main(String[] args) { double var[] = {21,40,61,85,100}; double min = var[0]; for(int a = 0; a < var.length; a++) { if(var[a] < min) { min = var[a]; } } System.out.println("The minimum number is : " + min); } }

**Output:**

The minimum number is : 21.0

##### conclusion:

So this is all about how to calculate sum and average of values in an array. We also learnt how to calculate maximum and minimum values in an array.
