Determining Set Size

A BitSet is a dynamically growing array containing bits. This dynamically growing structure has two values describing its internal dimensions: a size and a length. public int size() public int length() import java.util.BitSet; public class MainClass {  public static void main (String args[]) {     BitSet bites = new BitSet();     bites.set(0);     bites.set(1);     bites.set(2);     bites.set(3);          System.out.println(bites.size());     System.out.println(bites.length());   } } 64 4
