Jul 9, 2009 - "Could not find d main class:Arithmetic" means that your computer can't find the .class file.... are you sure that the compiling process was successfully carried out?... hope you already fixed this :)cheers

MrProgrampro Says:

Sep 5, 2009 - Nice one!Also, something I thought while watching your vid...You can make execution a lot easier with batch files (i think..)...well, I KNOW compiling would work, anyway...just go into notepad, and make a file:javac %1then Save As "Java Compiler.bat"Now, any .java programs you drag onto it will be compiled instantly! The same may work with a "java %1" program, although seeing as how normal batch files exit immediately when finished, I don't know :/..try it!Hope this helps (like you)!

Sep 7, 2009 - is it required to save the file as "arithmitic.java" or can you call it math.java or haha.java?

spongewardk Says:

Oct 5, 2009 - you can name the .java file anything as long as when you use javac you type the correct file. the new class file will be the same name as the class.

Flowzah Says:

Oct 6, 2009 - you have to use the exact class name as the filename.So if you do:class Math{the name of your .java should be Math.javahope that helped!

MrHeLmEtMaN Says:

Nov 30, 2009 - I copied your Arithmatic.java file the exact same way you have it but my file won't compile do you know why its doing this?
