sorry for delay :}
mCharacterName is a private variable. It should be accessable only from the class itself and not from ouside. This is a kind of variable protection from beeing changed or broken accidently or intentionally.
Therefor yor create a getter and seeter method to be able to get and set the state of mCharacterName. This is a common practise called ENCAPSULATION. Here a link for more information:
http://beginnersbook.com/2013/05/encapsulation-in-java/
The reason MAX_PEZ is public is that everyone should know how many PEZ can be inside a dispenser. The MAX_PEZ is a constant variable (uppercased) and it is marked as final, so it canΒ΄t be changed !!!
So everyone knows that our dispenser holds 8 Pez and canΒ΄t change this number, because it is final (protected from beeing changed)
Makes sense?
