Description
A MathVector object will be passed to your method. Return the 5th element inside of that object.
If you look in the file MathVector.java you'll see there is a way to extract the value of one element in the
array contained inside a MathVector object:
/**
* Returns the element at the specified index.
*
* @param index the index of the element to return
* @return the element at the specified index
*/
public int at(int index) {
return array[index];
}
use it like myObject.at(4); to get the 4th element. You did similar operations (with a different syntax) with
Matlab.
