   Need Help With An Exception
  Ok, I have a HW assignment. This shit is easy but I keep getting an error and I am not sure why! Please Help!!!!My Compiler: newest ver of NetBeansHere is my prompt(assignment): http://www.cs.unca.edu/~bruce/Spring04/csci201/assignment1.htmlHere is my code:/* * Main.java * * Created on February 9, 2004, 12:47 PM *//*** Name: Eric William Sopp** ** Course: CSCI 201 ** ** Purpose: In this assignment, you will learn to read data from the keyboard and write it  to the monitor.

  - ;  Right now I don''t have enough time to go through all that code.  However, I can give you a tip for finding the problem.  Use a debugger to see exactly where the violation is occuring. ;  post the commands you are giving to compile and run the program   "A soldier is a part of the 1% of the population that keeps the other 99% free"  - Lt. Colonel Todd, 1/38th Infantry, Ft. Benning, GA ;package Fortune.java;   Try dropping the ".java"And also make sure you execute as follows:java Fortune.Main    in the directory above Fortunei.e.:C:\Projects\Fortune> cd ..C:\Projects> java Fortune.Main    where "C:\Projects\Fortune" is the directory where, "Main.class" is.   Edit: The exception is caused because the java cant find your class!u r what u bcome [edited by - bcome on February 9, 2004 10:51:20 PM] [edited by - bcome on February 9, 2004 10:52:55 PM];  Sweet I fixed it! Thanks man. I didnt turn it in on time but I dont care, I figured it out ;  Gah. Got here too late. Anyway, "bcome" has the right info for you. An exception complaining "class not found" is a problem with your environment (/invocation), not the code itself. It means exactly what it says: the java interpreter couldn''t find your class.And yeah, the package declaration has to match the directory where the class is located. No .java at the end of your import statements unless you actually define a "class java" (silly you! It''s generally accepted Java convention that your class names should be capitalized, anyway), and no .class suffix when you invoke the java interpreter. "javac foo.java; java foo".And re pasting big blocks of code: Use the [source][/source].
