Hello. I'm a novice Java programmer. This is my first programming language and i just started on this book a few days ago.

I tried to follow the instructions given in the book but i got this error in my command:

C:\Users\shawnlim2010\My Documents\NetBeansProjects\OurFirstProgram\src\our first
program>java OurFirstProgram
Exception in thread "main" java.lang.NoClassDefFoundError: OurFirstProgram (wron

I've managed to compile OurFirstProgram.java successfully. But as you can see I am having trouble running OurFirstProgram. I'm not sure why. Would anyone be able to help?

Thanks.
