Unknown bro, your code runs perfectly. few curly braces were missing in your copied code. 
What IDE are you using? if you are using command line, try compiling all files separately.
Also if you are using eclipse, try refreshing the project as well ( elcipse had bug , dunno if they fixed it).
Andif your classes are in different packages, try importing the packages OR provide the full path of the classes including package like 

com.unknown.packagename.Player p= new com.unknown.packagename.Player();

your code gave me this output: ( copied and pasted)
