But what if you want to manually manage the heap?
But no templates. You need to do type casting back and forth. This is not
only awkward, but also inefficient.

But what if you want to write clean nice code?
Java
It's also easy to find 3rd party C++ libraries.
My point is, Java assumes that you don't know too much in computer science.
It is designed for the ease to use.
On the other hand, C++ assumes that you know much in computer science. It is
designed for performance.
What is the conclusio

Well, I am C++ guy as well as a Java guy doing research, but this is too much
hype for C++. IMHO, C++ and Java are the tradeoff of price and performance,
C++ is 2-5 times faster while taking 50%-100% longer time to develop. And
probably needs much more time in mantenance. However, it's nothing to do with
CS. Lang is just a tool. Given adequate lib, C++/Smalltalk/Java/C# can do
virtually the same job. My exp. is that as long as Java can do the job,
go with Java since we've got good computers. Fo

I think the security design and implementation is the one of the
major advantages of java.

People like to compare JAVA with C++ and blame JAVA lacks some C++ features.
JAVA is just designed that way (eg. primitive type is not an OO way for
programming). If it had everything C++ has then it will have every bad thing
of C++. They are both doing well in their own teritories. C/C++ may not the
best language at that time but may be the most successful one.

rocks!
