Is it a common practice to use public enum for containing default constants in c++?

seems to work fine It's a fairly common practice, to make sure a constant is really treated as a constant in all cases.
What C++ has a lot, that Java doesn't, is references to any type, even primitive types, and as a result of that,
code :
struct S {
  static const int i = 3;
};
void f(const int &);
void g() { f(S::i); };

Should Java enum constants be retrieved through "get" methods or public final fields or both?

will help you You cannot access the fullName through a static method. They are instance fields.
Your code is correct. You may wish to mark your String fields as final and rid yourself of the setXXX methods (since Enum values are traditionally immutable).
Are enums really constants ? Shouldn't the data members of enum be declared final by default?

it helps some times What is immutable, and what is static final by default, are the enum values (as to their visibility modifier, ie public, private or default, it is inherited from the declaration of the enum itself).
But these values are classes in their own right; and as such, this immutability does not hold for their instance variables, if any.
code :
public interface Foo
{
    int bar = 3; // bar is "public", "static" AND "final" by default
}
Print Java ENUM to lower case by default keeping enum constants in uppercase

I set three enum constants in a single enum variable, Is there a way to retrieve the enum constants from the enum variab

this will help You have to use [Flags] attribute and set enum value to be a power of 2:
code :
[Flags]
public enum Fruits
{
    Apple = 1,
    Mango = 2,
    Orange = 4,
    Grapes = 8,
    Banana = 16
}
Is it considered a bad practice to put all enum types within an application in a header file with other constants?

hop of those help? While sapi's answer isn't wrong, here's what I have a tendency to do...
A group of constants that are used across multiple files will go into a file. Let's say all my Foo constants go in FooConstants.h.
