Hi,
my question should be easy to answer for anyone who knows C++/Java and ADA.
Unfortunately I only know C++&Java :-(.

Question: What are the corresponding ADA keywords to the given C++/Java
features, and which keywords do exist in ADA which have no representation in
C++/Java, and what do they mean. I did have a look at the
http://www.adahome.com/rm95/ Ada reference Manual, but this would be a
longer way to go then I would like to. So could one of you who knows both
languages help me out?


C++/Java Keywords of interest to me:

auto:      variable has local (automatic) extent

abstract  (Java)  pure virtual

const:    functions values are not modifiable

explicit:    Constructors declared explicit will not be considered for
implicit conversions

extern:    Variable or function has external linkage, or linkage conversion
of another language

final    (Java) class, method cannot be derived from or overwritten

friend:     function or class has access to private/protected class members

interface    (Java)  concept for abstract interface suitable for multiple
inheritance

mutable:    Non-static non const data members. If declared mutable it is
legal to assign a value to this data member from a const member function

native  (Java) modifier used in the declaration of a method to indicate that
the method is implemented in another programming language

namespace:    obvious

package  (Java) obvious

private:     visibility for class member

protected:     visibility for class member

public:    visibility for class member

register:    "asks" compiler to place variable in CPU register

synchronized  (Java) modifier to specify thread-safe methods

static:    linkage for variables and functions

template:    set of parameterized classes or functions

virtual:    polymorphism for functions, for classes to disable multiple
members while using multiple inheritance

transient  (Java) modifier used in the declaration of variables

volatile:    type qualifier; object can be modified in the program by
something other than statements, such as the operating system, the hardware,
or a concurrently executing thread

Thank you very much in advance for any help!

cu,
alex
