We can determine the length of an ArrayList<E> using its public method size() , like

 ArrayList<Integer> arr = new ArrayList(10);
 int size = arr.size(); 

Similarly we can determine the length of an Array object using the length property

String[] str = new String[10];
int size =  str.length;

Whereas the size() method of ArrayList is defined inside the ArrayList class , where is this length property of Array defined ? Is it implemented by JVM or does it reside in any Java API class file ?
