Java: Variable Length Arguments
Sometimes when creating functions you don't know how many arguments its going to take.
This is done using an ellipsis (...).
Here is an example of a function which takes variable length arguments:
public static int SumOf(int...numbers){
}
As you can see this currently does nothing, so lets make it do something with the input:
public class Main{
public static void main(String[] args){
System.out.println(SumOf(12, 3, 91, 22, 334, 63));
}
public static int SumOf(int...numbers){
int total = 0;
for(int item : numbers){
total+=item;
}
return total;
}
}
You can see this outputs 525 as expected.
