Lines 15 16 instantiate two Characterobjects and pass character literals to the constructor to initialize those objects. Line 18 uses Character method charValue to return the char value stored in Characterobject c1. Line 19 returns a Stringrepresentation of Characterobject c2using method toString. Lines 20 21perform hashCodecalculations on the Characterobjects c1and c2, respectively. Remember that hash code values are used to store objects in hash tables for fast lookup capabilities (see Chapter 20). Copyright 1992 2002 by Deitel & Associates, Inc. All Rights Reserved. 7/7/01
