List of Syntax differences between Java and C++
I'm not looking for a pro con type list.
I'm looking for a list of programming syntax differences between Java and C++.
I'm currently reading a Java book, but so much of it is stuff I already know since Java is so similar to C++.
The kind of list I'm looking for is something like the following:
No Constructor initialize list -> superclass initialize on first line of constructor
Boolean condition statements
Labeled loop-breaks
No pointers ?????
No multiple inheritance

The list you posted are pro con list.
As I stated in my question I'm *NOT* looking for a pro-con list.

I'm not looking for std::list object type comparison with java list.
I'm looking for Language **Syntax** differences between Java and C++.
Please look at the examples I posted in my question.

Unfortunately, you're just going to have to _learn_ the syntax of Java, and make your own comparisons. The synaxes (sp?) between the two languages, as you've already stated, are very similar; HOWEVER, in order to understand fully the syntax of Java, you must understand the semantics behind the syntax. For instance, the "package" keyword. Inside a Java class, the "package" keyword indicates that the class belongs to the class specified by the string immediately following the keyword. There is no *true* syntactic equivalent in C++. It's just a matter of the two languages being different. Rather than trying to learn Java in the way that you're doing:
"Java is C++ with the following differences: ..."
You should learn Java and treat it as its own language, its own syntax, semantics, everything. Learn the Java programming paradigm, just as you've learned (one of) the C++ programming paradigm(s), and it will serve you well. Otherwise, you'll be wrestling with Java in an attempt to fit it into a C++ - shaped box. As the quote says, "One can write FORTRAN code in any language."
As far as your original question, you might, rather than expecting someone to give you a list, try observing a difference between the two languages, and then bring the question to EE like this:
"I'm learning Java, and trying to understand X. I know how X works in C++. How does it work in Java?"
And you'll probably obtain answers that are much more useful to you.

guitaristx,
I'm sorry, but I know what works for me.
I've been programming for over 15 years, and I know what's the best methods that works for me, and what will not work.
Reading a Java book that mostly has the same information that I've learned in C++ will just bore me to death, and I will find it hard to finish it.
I do better at learning languages by reference, then I do by reading a book cover-to-cover.
So my question still stands as-is.
If no-one can provide the link, I'll request a deletion of this question.
I'm just looking for the syntax differences, and I'm not really concern with the details.
I'm just looking for something I can use as a reference, and perhaps add my on notes to it.

And I know people with similar attitudes, whose Java code I've been forced to maintain. Their Java is written in C++, because they considered Java to be a "sort of like C++" language, and tailored their code to be as C++ - like as possible. This is a Bad Thing. If you're not into reading a book or tutorial, I'd recommend reading the language specification:

I expect that I will be making similar mistakes. I would expect that even if I did read a Java book cover-to-cover.
I've seen plenty of C programmers that have taken C++ courses and read C++ books, but still produce C style C++ programs.
It's not as easy as you think moving from one paradigm to another.
The trick is learning to *continue* to progress to the new paradigm as you go, and not expect it to happen over night.

I had a hard time looking for the Java to C++ convertion but I think the link is still informative you just do it in reverse.
Just a question, why do you plan to move to C++ ?
It would be better to maybe check C#, since the paradigm goes to C > C++ > Java > C#.

I think you misunderstood me.
I'm not moving to C++. I'm moving to Java.
I'm currently a C++ expert, and I'm ranked in top three in the C++ Topic area.
I now want my Java skills to be equal to my C++ skills.

Oh now I see, sorry for the confusion I was actually having a problem on my own quetion in a seperate thread :)

I found a link in the java sun site that had some really good information on this topic (C++ <> Java)
http://java.sun.com/docs/white/langenv/Simple.doc2.html
It's a White Paper that not only describes some of the differences, but also includes the motivation behind the change.
