tell me how to start with C++ and JAVA,thanks very much:)
At first decide to learn C++ OR Java. You will not manage both at once.
It's too much. To learn one programming language you need practice in it
and this takes some time. As some concepts are similar in C++ and Java
and some completely different, you will get completely confused if you
want to do both at once. I don't belive it's a good idea to to try both...
So, how to decide what to learn:
First, what do you need it for? Do you need high performance
calculations? Trying to get the last out of your hardware, for the cost
of complexity and to care about everything on your own? then go to C++.
If you want to be sure your applications will run on a lot of different
platforms and operation systems (where there is a Java Virtual Machine
(VM) existing for) without modifications, and accept a decrease of speed
for it, then you can go for Java (or even C# if you accept that mono -
the Linux implementation if it - is not 100% finished yet).
Second, if you need to do driver development, everything close to the
hardware, kernel or operating system development (e.g. for Linux) then
go for C++. If you want to build Server Web applications then go for Java.
This was a very simple view of the plus and minus of this two languages
and for sure not complete. But if performance is not an issue I would
recommend you to go for Java, as it is multi OS and platform and
computers today are normally fast enough to deal with it. You do not
have to care about everything on your own (Memory handling, Hardware
access). This is all doing the VM for you. But on other hand side, this
is limiting of course as well. So it really depends...
If you found out what you will go for, look for a book to learn the
language (not one of the 21 days boods, at least I don't like them) and
work your way through it. and then practice and enjoy ;-)
