David, the long is a primitive 64 bit two's compliment integer datatype (see http://java.sun.com/docs/books/tutorial/java/nutsandbolts/datatypes.html for more information on primitive datatypes). The Long class is a "wrapper" class that provides built in methods for the long datatype just as the Integer class is a "wrapper" class for the integer datatype (see http://java.sun.com/docs/books/tutorial/java/data/numberclasses.html for more information on Number classes). So instead of using Integer use Long.

(For your own exercise - this is not a homework) Modify ClassAndObject.java as following. * Create another object instance of Long class using new keyword. * Display it using Sytem.out.println(..) method. What does Long class mean? Or is this a typo and it should be integer class. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/javaprogrammingwithpassion?hl=en -~----------~----~----~----~------~----~------~--~---
