Should be pretty straightforward.<br /> <br /> b) Find out what an instance variable is. Basically what is the difference between a static variable and a non-static variable?<br /> <br /> c) Run it and find out. Put the code in part C in main, and IdentifyMyParts in a another file and give it the same name as the class name. If you don't understand the output trace it on paper and keep in mind what a static variable is. If you are still stuck, come back and ask specific questions about its behavior.<br /> <br /> Please don't post homework, expecting to be spoon-fed the answers. No one here will do your homework for you, and it will not help you.<br /> <em><span style="color: Blue;">Just my 2 bits</span><em><br /> <br /> <br /> <br /> </em></em> http://www.programmersheaven.com/mb/java/315196/315223/re-what-would-be-the-output/#315223 Wed, 14 Sep 2005 09:59:30 -0700 Java
