real world java

[Zosden]

I know java is suppose to be the savior of programming and with all these examples of how its better than c++ yet I haven't seen it used anywhere could someone please post some examples of where java is used or some apps that use it

[Eranga]

I'm not remember the applications developed in C++. But in Java a lot.

1. Mars Pathfinder Mission - From 1997, NASA used Java technologies communicate with Pathfinder from the Earth. Still the used it.
2. Hubble Space Telescope - In result of Java use in Pathfinder in 1997 they decide to use it further more.
3. Sony Online Ventures - Completely use server-side Java technologies
4. American Information Systems - Data record system of all people in US, data processing with Java

Those are some application I've remember that use Java. There are hundred of such applications can be found today.

Ok thanks but it seems none of those apps are mainstream I know almost every major software is written in c++ anything from firefox to console games to most of games

This sure smells like a troll.

You got a citation for this bogus claim?

There is no one true language, no more than there is only one true choice between blond, brunet or redhead.

C++ fell out of favor because while it can generate faster executing code, sometimes, it is harder to get a group of programmers to be effective in it. Firefox depends on its rendering speed, but a lot of it is written in Chrome, a meta language that makes it easy to customise the look and feel.

Applications that require speed over all else are not where most of the code is written these days. Processors are getting faster every day, and most modern systems have two or four processors. So you optimize the cost of getting the application written.

Some games, rendering engines, embedded systems, and other things have different requirements, and thus use different languages.

Very little, if any, of the Web 2.0 stuff is written in C++, a huge amount is written in PHP, Ruby, Python, Java or perl

Most games are written in C++ and I don't know why it is. But at the time C# also used.

Comes to the major software, not much are developed in C++. Since Microsoft plays a big role here, .Net(specially C#) plays a major role. And Java too. There are few open source software written in Java.

Games get written in C++ by experts because performance is critical in games. Gamers spend huge amounts of money overclocking and installing dual SLI systems were each video card costs as much as a low end PC.

Having two extra frames per second in a game is a big deal, and it converts to player satisfaction and thus money.

Console games are very special as well, they are sold to millions of users, and performance is a big deal.

Its hard to get great CGI for realism without serious tweaking.

But both PC games and console games are written by a very small number of highly paid experts. That is not the real world.

I worked for a company with several thousand developers. One of the best of all that I knew went to work for EA in California. He was much better than all but five or so developers out of the several thousand.

The real world developer is not as smart as Bill Gates, or Bill Joy. And performance can be had by throwing another quad processor system into the rack. A new server might cost $10,000, which is only a month of a professional developer's salary.

C# is essentially Java relabeled by Microsoft so that folks won't use Java from Sun. There are a few differences, but nothing that a good developer would take more than a week or two to spin up on.

In 99% of all systems, its the people that are the expensive resource. Not hardware.

The cost of the people is great for developers in India and other lower cost places, not so good for developers in the US.

Thanks that was very helpful.
