Code example for ObjectStreamField

	 * The bits in this BitSet.  The ith bit is stored in bits[i/64] at 
	 * bit position i % 64 (where bit position 0 refers to the least 
	 * significant bit and 63 refers to the most significant bit). 
	private static final ObjectStreamField[] serialPersistentFields = {
			new ObjectStreamField("bits", long[].class),
	 * The internal field corresponding to the serialField "bits". 
	public long[] words;
	 * The number of words in the logical size of this BitSet. 
	public transient int wordsInUse = 0;
	 * Whether the size of "words" is user-specified.  If so, we assume 
	 * the user knows what he's doing and try harder to preserve it.
