You understand little. Does C/C++ remove unnecessary blocks from your code while the app is running? I think not. Also with C/C++ you're always programming to the OS.. the standard libraries are way too small.. so people end up reinventing the wheel.. badly.

Eclipse, IntelliJ IDEA, Netbeans..

Dude! This is NOT a matter of opinion! There are zillions of libraries INCLUDED with the Java platform.. moreso as you branch out!
With no extra instalation you can zip/unzip files, you can do GUIs, you can do networking, concurrency, concurrent data structures, regular expressions, ...
I'm just talking about what's included with Java. C++ has STL + iostream + C libs. Come on! No comparison here.
You'll say.. "use third party" but which 3rd party should you use? How are those skills transferable when you go to a new place where they don't know/use that library.
No comparison.. Java is waaaaaay better that C++ in this department.

We were a C++ team. We switched to Java (back in 1998 when Java wasn't all that good and had really crappy dev tools). In spite of our not knowing what we were doing in the new environment and considering we were a newly formed team of C++ programmers. It is quite surprising that our productivity leaped over the roof! Not only did we write code faster in Java.. we were also able to do things (like threads) use libraries (like OSS libraries from the Internet.. yes.. even then) that in C++ was just hard or clunky and therefore was usually avoided.
Also Java culture is of library use. C++ culture is invent your own. Java culture is OO. C++ culture is micro-optimization. Java culture is multi-threaded. C++ culture is make it simple 'cause the language is a bitch! (And this is coming from an experienced C++ programmer)

abstractions?? C++ has less abstraction and more low-level programming!
