.java to .jar file

Hi guys!
I have a problem i think i dont know how to do this little thing
I have searched around the web, but i cant find anyone to explain it how to
and where to put this code down here in order for the compilator to convert it
from .java to a .jar file so the program or games i do in neatbeans can be executed in
my mobile phone!
Anyone can help??? The code is this one:
jar cf jar-file input-file(s)

 

.java to .jar file

As a side note to Easy Rhinos comment, you can only jar .class files, meaning that you need to compile all the .java files and them jar the .class files resulting from the compilation. Example:
Code: javac Test.java jar cf Teste.jar Test.class[/quote]
