java, c or c++

choice between c and c++ is pretty obvious if the program is even
moderately big.

how does java score in comparison to c++ in terms of efficiency ?
i guess java definitely has more libraries, more verbosity (for
clarity to programmers) etc etc.
The only concern is efficiency. How does java compare with C/C++ on
that ?

This page has a fun comparison of a variety of languages with a
variety of benchmarks:

It depends on your target. On the whole, I'd agree with you
(and it's no accident that, knowing both languages well, I do
most of my work in C++). But in cases where absolute
reliability isn't important, and portability---even to systems
you might not know exist---is, Java has its place. When you
have to deliver client software to a large, heterogeneous park,
you do gain programmer productivity by only having to compile
and test on one (virtual) platform. You don't have the
reliability of having actually tested on every target, but if
the code isn't critical (e.g. just some flashy interface, to
make things look good), the JVM is generally sufficiently
reliable for that. Thus, for example, I've seen more than a few
applications which use Java for a comfortable interface for
editing their configuration files, or displaying an overall view
of the system: which machines are running, which aren't, etc.

I wrote a Jython class that inherits from a Java class and (thats the plan) overrides one method. Everything should stay the same. If I run this nothing happens whereas if I run the Java class it says: usage: java fit.FitServer host port socketTicket -v verbose I think this is because I do not understand the jython mechanism for inheritance (yet).

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
