I need to pass in a Double number(class) into a sum class' constructor. I tried passing in an ArrayList of numbers . Basically the class sum can pass in any number of number objects. Need help building a versatile constructor such that sum can take in at least two number objects. Then the sum class need to add all of the number objects. (JAVA)

Basically the sum constructor can take any number of double:

//Constructor

class sum(num(obj), num(obj)){

}

method add(List){

iterate through all the number objects and print out the sum

}
