"Can you list me some features of the java language"(Interview question )

A plethora of libraries on several topics are standardized along with the fast evolving Java including GUI, threads, networking (TCP/IP, URLConnection), XML-handling, JDBC etc. in J2SE and servlets, JavaMail etc. on J2EE.

As a language, C++ is more mighty (and has therefore more caveats, gotchas etc.)

C++ has exceptions.

C++ is object-oriented. The lack of a root Object class, and the ability to write procedural code, does not mean C++ isn't object-oriented. It supports abstract data types, inheritance, polymorphism, etc. What's not object-oriented about that?

C++ doesn't have garbage collection. Class developers manage their own memory.

C++ doesn't have as extensive a collection of built-in libraries as Java.

C++ does allow multiple inheritance of implementation and operator overloading; Java does not allow either.

Like I said a while ago: written sarcasm doesn't work. qed

Btw: >>supports<< is the word here. It supports, but doesn't enforce. It ought to be OO.

It does if you put <sarcasm> tags in/

O-O isn't black and white, it's a continuum.

Smalltalkers might say that Java isn't object-oriented, because they still have primitives. I'd say they're wrong.

Look at this forum sometime and see how many people cram procedural code into a main and still call themselves "Java programmers". Java doesn't enforce it, either. There's no way to mandate O-O thought.

i think you could argue function pointers can count as some type of reflection

My answer:

"Your joking right?"

Would you hire a mechanic to work on your car if you had to ask him if he knew what a wrench was, and your second question was how's a wrench different from a hammer.

The answer to these questions aren't important in an interview. It tells the interviewer nothing about your skills or talent. It does raise a huge red flag if you can't answer them.

Maybe, this is a crappy job. They are looking for the cheapest person to do the easiest work, and they only care if you know your ABC's.

I would guess that you're looking for your first job as a Java developer, and are happy to take what you can get. Earn some experiences.. etc.. etc.. etc..

Still, if you get this job. Write in the forum three months later and tell us of what you think about working there. I think I know how that posting will sound.

I find these the most prominent characteristics. Java

1. is propriatory, owned by Sun.

2. is dynamically compiled.

3. has automatic memory management.

4. is portable (highly defined, has standard GUI and multi-threading)

5. lacks address-of operator and operator overloading.

6. makes distinction between subclassing and subtyping.
