yes, of course. what did you expect? That's what it's supposed to do, unless you tell it different.
did you mean, you expected it to move it to a different output folder? or did you mean you expected it to create a .jar archive for the package?
How exactly did you expect it to "create" the package?

No, that's not quite right. The class file will always be put into the same directory it's source file is in, UNLESS you specify otherwise.
When the directory DOES matter is when you link it into an application (on the class path). Here, you specify the directory that the base package is in, and the classes must be in appropriate directories beneath that base directory in your classpath.
So javac does not actually generate the directory structure necessary for your packages to be linked into an application or a compile - it just puts the classes where the source files are. BUT, if you put your source files in the correct package directories before compiling, then when the class files are output, they will automatically be in the right places, by virtue of the fact that the source files were in the right places.

Use the -d argument, just as I said before.
