In Java, such entities must belong to some given type, and therefore must be defined inside a type definition, either a class or an interface. Functions and methods can also guarantee that they will not modify the object pointed to by a pointer by using the "const" keyword. In Java, for the most part, const-correctness must rely on the semantics of the class' interface, i.
I do, but I get a lot of email. However, sometimes I get overwhelmed. Some messages are lost in my mailbox, some are delayed until I can find time, some are delayed until I get around to answering a set of related messages this often happens to comments about potential errors in my books.
Unfortunately, longer and more thoughtful messages are more likely to get delayed than simple ones that have simple answers. Also, if you mail me, please try to make sure that I can reply to you.
I really hate it when I have written and sent a reply, just to find that the return address is invalid or inaccessible.

If in doubt, consider the style and contents of the suspect message, check for other postings in the forum, or ask. What is so great about classes? Classes are there to help you organize your code and to reason about your programs.
You could roughly equivalently say that classes are there to help you avoid making mistakes and to help you find bugs after you do make a mistake. In this way, classes significantly helps maintenance. A class is the representation of an idea, a concept, in the code.
An object of a class represents a particular example of the idea in the code.Since performance optimizing is a very complex issue, it is very difficult to quantify the performance difference between C++ and Java in general terms, and most benchmarks are unreliable and biased.
Given the very different natures of the languages, definitive qualitative differences are .
