A null pointer exception is caused when the Java program tries to reference something that doesn't exist. Hence the null pointer part.  This sounds to me like there is a problem with the applet, not your computer.  Is it working for others in your class? I would e-mail the instructor right away to let  s/he know you are having problems, that way, if you are unable to resolve the issue, your instructor is likely to be understanding if you get a little behind.

Jbuilder is just a development environment. To use it, you must give it a valid java runtime environment. That environment contains the entire Java language, so you don't need to install something else.\n\nShort of specifying what the actual problem is, the only thing I can say is that you are not using the Scanner and JOptionDialog properly.\n\n(Scanner does not seem to be an actual class from the original Java API. Did you mean something else?\n\nEdit: The Scanner class is a new class in JRE 5.0 - Just ensure JBuilder is using JRE 5.0)

Try reinstalling the program. The error seems to be an installation issue. Another possible reason could be that you changed the operating system in the formatting procedure. If that is the case check if the program is even compatible with the current operating system that you are runnning.

First make sure that the class which contains ur               main (String args[])\nfunction hass got the same name as ur file name.\nIf u r using command prompt to run ur program make sure u have set the classpath properly or copy ur file to the bin directory of the jdk installation and run it from there.
