# Java - sum all ArrayList elements

3
points

In this article, we would like to show you how to __sum all the elements from ArrayList__ in __Java__.

Quick solution:

```
List<Integer> numbers = new ArrayList<>();
int sum = 0;
for (int number : numbers){
sum += number;
}
```

## Practical example

In this example, we add the value of each `number`

from `numbers`

ArrayList to the `sum`

variable.

```
import java.util.*;
public class Example {
public static void main(String[] args) {
List<Integer> numbers = new ArrayList<>();
numbers.add(1);
numbers.add(2);
numbers.add(3);
int sum = 0;
for (int number : numbers){
sum += number;
}
System.out.println(sum);
}
}
```

Output:

`6`
