Java 7: What's In It For Developers 338

GMGruman writes "After five years of a torturous political process and now under the new ownership of Oracle, Java SE 7 is finally out (and its initial bugs patched in the Update 1 release). So what does it actually offer? Paul Krill surveys the new capabilities that matter most for Java developers, from dynamic language support to an improved file system."

    Arguments for slow Java are so 1990's. Every Java application, desktop or otherwise, I have written has been very snappy, very responsive. Swing has always had places where you can get caught making your own application slow to load or slow to respond. I believe that the community and Sun have really ushered in conventions to mitigate that. SwingWorker (part of core Java Swing), Timing Framework [], JPA (especially our friends at Eclipse), and other community frameworks have really changed the way coders write Java desktop applications in ways that avoid a lot of the pitfalls that came with the 1.1, 1.2 and so on versions of Java.

    I think this is the reason why Oracle really needs to embrace the community. It has been because of them that Java has gotten better and faster with each release. People who still talk about how slow Java is and how crappy Swing is, are still living in the past. Is it the perfect platform? No, but it has gotten multiple times better than where it was.

    once you have programed in Java for a few months you are incapable of writing functional C++ code

    Having been a Java developer for eleven years now, I still write C++ with few memory leaks and a couple of passes through a debugger usually fixes that. I am not sure why people believe Java makes you a bad programmer. Java, C#, and C++ all follow the same design patterns, they just use different methods on getting there. It is really not that hard to remember, hey in this language the object is GC and in this one it isn't. A singleton design pattern in C++ and Java look exactly alike and function exactly the same. Java you don't have to worry about cleaning the mess up and in C++ you clean it up in the destructor, c'mon some people make it out to be the difference between gutting a fish and brain surgery. It's all syntax sugar, a lot of people need a new argument.

    "Write once, run anywhere" was like communism -- an idea that sounds nice in theory in some ways but utterly fails to work in reality.

    True, if you hardcode C:\something or /somethingelse in your app. I've never had cross-platform problems, either on big server side applications or trivial desktop ones. So I guess 'utterly failes to work in reality' is somewhat dependent on the developer.

The best defense against logic is ignorance.
