Java spread operator

Question

I am not sure of the vocabulary I am using here, please correct me if I\'m wrong.

In Javascript, I had the following code:

let args = [1,2,3];

func         


        

Answer 1

In java there is concept of Variable Arguments, using which you can pass different numbers of arguments to same function.

I am taking your code as an example :

public class Foo {
    public int doSomething (int ...a) {
      int sum = 0;
      for (int i : a)
           sum += i;
        return sum;
    }
 }

Now you can call this function as :

doSomething (args)
