Yes. I understand but my goal is to send a java file to somebody who is not
even a newbe.
In window for example:

------------ start it.cmd -------------------
javac hello.java
Wait one second please
pause >nul
java -cp hello
:EOF

Two things:

You really should get in the habit of naming your classes with an upper-case
first letter: Hello.java

-cp takes an argument, in this case the period (.) character. Hence,
java -cp . Hello

Don't forget the dot.

You still need to understand the issues highlighted, even if your recipient
doesn't. Failing to name a class, as in your first example, would not help
your recipient. Leaving out the argument to the classpath option ("-cp .")
also won't help anyone.
