Keyword `void`

is intended for functions which don’t `return`

anything.

For returning anything else we’ve gotta declare which datatype a function must `return`

.

Here’s a **sum()** function example for the `int`

primitive datatype:

```
static final int sum(final int... values) {
int total = 0;
for (final int v : values) total += v;
return total;
}
```

Based on your post and avoiding advanced syntax you can do

```
// Calculate the sum of 3, 4 and 5
int total = sum(3, 4, 5);
int sum(int a, int b, int c){
return a + b + c;
}
```
