We can determine the length of an
ArrayList<E> using its public method
ArrayList<Integer> arr = new ArrayList(10); int size = arr.size();
Similarly we can determine the length of an
Array object using the
String str = new String; int size = str.length;

Arrays are special objects in java, they have a simple attribute named

length, which contains the number of components of the array.
lengthmay be positive or zero.

A clone of a multidimensional array is shallow, which is to say that it creates only a single new array. Subarrays are shared.
- All the members inherited from class
Object; the only method of
Objectthat is not inherited is its
