Using size of an array list

When I calling the size method of my ArrayList, I get the error:

size has private access in ArrayList.

Any advice on this?

ArrayList<String> sAnswers = new ArrayList<>();
int arrayL = sAnswers.size;

There is no accessible size variable in List. It's a method

Access it like sAnswers.size();

size is a private variable in List. Use someList.size().
length is a public variable in an Array. Use someArray.length. 

ArrayList<String> sAnswers = new ArrayList<>();
int arrayL = sAnswers.size();
