static variable

[Carmen Sei]

does static in C++ is exactly the same as in Java?

the following static variable is Class variable that I can call by
Class Name

Configuration.RemoteType = xx;

#######################

class Configuration {
public:
Configuration();
void Initialize();

public:
static RemoteType RemoteType;
static ControllerType ControllerType;

};

Most probably not - static is a heavily overloaded keyword in C++. In
this case (class static data members) I believe the meaning is similar
though. Note that you need separate definition/initialization of static
data members outside of the class definition in C++, not sure about Java.

the following static variable is Class variable that I can call by
Class Name

Configuration.RemoteType = xx;

In C++ this reads:
Configuration::RemoteType = xx;

#######################

class Configuration {
public:
Configuration();
void Initialize();

public:
static RemoteType RemoteType;
static ControllerType ControllerType;

You cannot have the variable name same as the type!

The question is not very much clear. In what sense are you comparing
the two. If you mean that you can acess the variable without
instantiating an object, I think yes they are same but the systax is
different.

Java: ClassName.Staticvar = SomeValue;

C++: ClassName::StaticVar = SomeValue;

Hope this helps.

Not really. To begin with, many of the contexts where you might
use static in C++ don't exist in Java.

Static member variables in C++ are fairly similar to static
member variables in Java, at least if you abstract the dynamic
loading of Java.

the following static variable is Class variable that I can
call by Class Name

Configuration.RemoteType = xx;

class Configuration {
public:
Configuration();
void Initialize();

public:
static RemoteType RemoteType;
static ControllerType ControllerType;
};

The syntax is different in C++. There is no instance of the
class type itself, and you use the scope resolution operator to
access static class members, e.g.: Configuration::RemoteType.
(Alteratively, if you have an instance, you can access the
variable just as if it were a non-static member of that
instance.)
