What command are you using at the command line to run the compiled file? If the file is named FirstProgram.java, the command to compile is:
> javac FirstProgram.java
Then to run the program
> java FirstProgram
Note, the '>' is intended to represent a prompt, not something you should type at your actual command prompt.
You may post the actual session from your command shell using copy/paste if you'd like. That might be helpful.

Hello.
Also, if you are using packages then you will need to invoke the class along with the package name.
For example, if the class is com.abc.Class1 then you will need to type "java com.abc.Class1" where com is the sub-directory in the present directory.

Check the location of your .java files, are there .class files there also?

Also, check out this video on Youtube and follow the instructions carefully.
