## In this Programme, you’ll learn Program to Calculate Average Using Arrays in Java.

To nicely understand this example, you should have knowledge of Java Program

#### Program to Calculate Average Using Arrays

public class Average { public static void main(String[] args) { double[] numArray = { 45.3, 67.5, -45.6, 20.34, 33.0, 45.6 }; double sum = 0.0; for (double num: numArray) { sum += num; } double average = sum / numArray.length; System.out.format("The average is: %.2f", average); } }

**Output**

The average is: 27.69

In the above program, the `numArray` stores the floating point values whose average is to be found.

Then, to calculate the `average`, we need to first calculate the `sum` of all elements in the array. This is done using a for-each loop in Java.

Finally, we calculate the average by the formula:

average = sum of numbers / total count

In this case, the total count is given by `numArray.length`

.

Finally, we print the average using `format()`

function so that we limit the decimal points to only 2 using `"%.2f"`
