It is.

You can put a class declaration inside a class.

I will say that:

C                        Java

#define X 1              No equivalent
#define Y 2
#define Z 3

const int X = 1;         public static final int X = 1;
const int Y = 2;         public static final int Y = 2;
const int Z = 3;         public static final int Z = 3;

enum XYZ { X, Y, Z };    public enum XYZ { X, Y, Z }

Assuming ANSI C and Java >= 1.5.
