Question

Assume that the following numbers belonged to an ArrayList called values:

5, 23, 45, −3, 17, 18, 100

Which of the following would determine how many elements are in values?

a	int numElements = values.length;
b	int numElements = values.length();
c	int numElements = values.size();
d	int numElements = values.size;
e	double numElements = values.size;

Answer 1

ArrayLists are objects which implement the java.util.List interface, and therefore must implement the interfaces methods.

The List interface uses a .size() method to measure the number of elements, so ArrayList implements it's own version of this method which you can use to determine the number of elements in values, with values.size()
