private: a private member can only be reached from within the class it is declared in.
friendly/default: a member with no access modifier can be reached from all classes that are in the same package/folder.
protected: same as friendly/default and, in addition, the member can be reached from any subclass in any package/folder.
public: the member can be reached from any class anywhere.

Hope this helps!

And just a note, friendly is a Cism and is not a keyword used in Java. From what I understand, friendly and default/package access are similar but not completely identical.
It is sorta covered in the JavaRanch Style Guide.
