In the following code, is double[] an array or what would you call it if you were talking about it? thanks



public double sum(double[] list) {
double s = 0;
for (int i=0; i < list.length; ++i)
s += list[i]
total = total + list[i]
return s;
}

ofcourse, it is an array.
A double array to be precise.

It's a double array that is passed as a parameter to a method.

See: The Java Tutorial - Arrays

Please use a meaningful subject line instead of "simple question" when you post a question. Imagine what the forum would look like if everybody used "Help!!!", "Question..." etc. as the subject...

I have made plenty of them.

1. An array is considered an object in java.
2. If it looks like an array, it is an array.
3. Arrays look like [].
4. You might say an array of " ... "
5. In this example, if you said and array of doubles, folks should grasp what it is you are talking about.
6. I think you can change your own subject line, I am not sure. Use the pencil and paper icon, see what happens.



:it compiled !


"The differential equations that describe dynamic interactions of power generators are similar to that of the gravitational interplay among celestial bodies, which is chaotic in nature."
