  10 Reasons We Need Java 3.0
Subject:   Include some of the good parts of C++

I am a C++ programmer as well as a Java programmer. I'm always wishing I had some of the features of C++ available when I write Java.


1) The "const" modifier. I have never been able to work out my Java does not have this.


2) The advanced features of the STL - iterators and algorithms particularly. I know there are implementations of the STL in java but I'd like to see the features of the STL made standard in the java.util package.

    But I think const-ness is a very good idea. C++, it can be a real pain to properly implement proper const-ness on an object. Determining what methods change state and what ones don't can take a lot of time. That's my only problem with seeing this feature in Java.

    Just like access control, const-ness is one of those nice-to-have features that raises the hurdles to getting a class ready for prime time. A "proper" C++ class is a pain to build. Overloading assignment operators, default constructors, copy constructors, destructors. It makes you not want to create a new class.

    A nice part of Java is that you don't need to be a language lawyer to write code that works as a class is expected to.

      Well not quite everything, but most things.

      Const is not worthwhile - the vast majority of variable I use are const.

      Fully identifying this would be painful.

      I just worked on some C++ code which would not compile after a compiler/STL version change because of a great many things, including changing interpretations of const.
