Simple package creation

I am using packages for the first time here and would like to know some basic understanding of them. I am using a Mac which shouldnt really matter, but anyway...I have a folder on my desktop called lab4, within this folder is another folder called csci1902 and a README.txt file, then inside the csci1902 folder is another folder called lab4. Inside this last lab4 folder are where my .java files are located. I was told that all I really need to do is put package csci1902.lab4; at the top of all my source code. Is this correct? and that is all? I have to do this so when we hand in the code, the TAs can run a script file and grade them all. With that at the top of my files, they will all be in that packge? Thank you.

kasey
