Define "better".

Going to Java will be easier.

Which one will educate me the best?

Define "best".

Well, I mean "better" and "best" in a very general sense, whichever
sense you want to interpret it on. More useful, more fun, more
educational, etc; or, as you already suggested, easier. Thanks.

The reason you are asking this here is that you have already
decided for C++, which we all know is the best programming
language.

Not quite. I also posted it on comp.lang.java. programmer. I really
really can't decide!

It depends on what do you want to do with C++ or Java.

I've spend several years with Java and becoming interested in C++.
They are strong at different kind of applications.

What kind of applications do you want to develop next?

Illogical.

There is no decision to be made. C++ is the true way.

Well, what is it you want to program?

You want to program 2D games? Java may be the way to go.
You want to program 3D games? C++ may be the way to go.
You want to write device drivers? C++

C++ is a more generall all around language that will allow you do do
anything, but with a cost. The cost of a much longer and steeper learning
curve. Java will get you writing applications faster, but for some things
you just won't be able to do it in Java or will have to find a library
written in some other language (such as C++) that interfaces into Java.

Good trolling post :)Obviously the answer would depend on the group
you posted this. You should have cross-posted the question, just for
some fun :) There is nothing that you can do in C++ that you can't do
in Java (except write low-lever drivers perhaps). Everything that you
can do in C++, you can do it much easier in Java with standard
libraries that support threading, networking, GUI and much more. Also,
the java app with GUI and networking will run only every OS that has a
JVM. In C++ you have to hunt for libraries, build them, and there is
no guarantee that you will get a portable product in the end.

Can you break the class hierarchy and just hack in some old
school procedural code in Java?

If you already know Python, you will probably find Java easier to learn than
C++. Learning C++ will take more time, and will be more difficult. However,
once you know C++ you will have a much better understanding of low level
details that goes behind the scenes while your program runs, than Java,
which hides a lot of low-level details from you.

Then, once you already have wrapped your brain around C++, you will find
Java easier to learn next, and you will learn to be a better Java
programmer, because you will have a better understanding how the Java VM
works than someone who learned Java without known C++.

If try to learn C++ after learning Java, you may find it a bit of a rough
going. Your existing Java-oriented mindset you may make it more difficult to
learn important C++ concepts than if you were to approach C++ from a neutral
viewpoint, without already acquiring the Java way of looking at things.

Both of course. Both are important contemporary languages that a
professional programmer ought to have at least some basic knowledge of.

Which one do you think will be a better transition for a Python
programmer? Which one will educate me the best?

Any Lisp dialect.

You can malke the class final and make everything static.

There is nothing that you can do in C++ that you can't do
in Java (except write low-lever drivers perhaps).

There's actually a lot: programming by contract, for example, or
intelligent management of locks. Or distribute a program for
which you can give reasonable guarantees of reliability on any
platform on which it runs (i.e. no dynamic linking).

I work mainly on large servers. I can't use Java for
reliability reasons; my code must work, every time.

Everything that you can do in C++, you can do it much easier
in Java with standard libraries that support threading,

Threading is actually considerably easier to do right in C++
than in Java.

networking, GUI and much more.

GUI is easier in Java. I've had no problem networking in C++,
and all of the large servers I'm familiar with (e.g. Apache,
etc.) are written in either C or C++---never in Java. When I
wrote the server for dynamic allocation of IP addresses
(networking), we used C++ for the server itself (for reliability
reasons, mainly---we guaranteed up time), and Java for all of
the interface code around it (mostly beans under WebSphere).

Also, the java app with GUI and networking will run only every
OS that has a JVM. In C++ you have to hunt for libraries,
build them, and there is no guarantee that you will get a
portable product in the end.

And if the code is only supposed to run on one machine, or a
small set of machines? With care, it's possible to write C++
code which ports easily to most Unix machines, and for large
scale servers, that's all you're interested in anyway.
