[Closed] Question for Java programmers

I use generics, which I think were added in 1.5

i.e. List<RandomStuff>

Not used Java in a while, mostly C# these days, but yeah generics were used everywhere.

Maybe ask the same question here:

I am just reading up on generics, and it strikes me that a lot of people would probably not use them out of habit. But then again, they've been there a long long time now and I am well out of touch.

I'm so screwed with my job hunting.

I thought the "for each" iterator in 1.5 was great, but I haven't used Java for a few years now. Switched to C# in my final year at Uni.

Generics is where I see most use of the new features.

Generics, and annotations when we do EJB3.0 and JUnit4.

And those neat for(Object o : myList) loops too.

Second/Third Genetics, very useful for improving code quality

I also like JSR 223 which allows scripting for the Java language.

If you are thinking of developing UIs in java take a look at [url= http://www.jidesoft.com/ ]JIDE[/url]

I reckon Java is dying a bit, especially on the desktop. C# is shooting ahead with the new features like LINQ and functional programming.

C# still gaining ground cos it's new. How is functional programming new tho?

I read about generics this afternoon - all cool stuff 🙂

Java is a middle tier language. I think a lot of problems come from the difficulity of intergrating with COM or DLLs.

Java dosn't seem to have as many good visual components as C# or Delphi.

Saying that it is possible and I use it for windows desktop development

Yeah [url= http://en.wikipedia.org/wiki/Functional_programming ]Functional Programming[/url] isn't a new concept, but few commercial languages have built-in support for it and there is a growing interest in it as people look at Haskell and F#.

C# already supports closures, lambdas, expression trees and type inference.

So you can easily do stuff like:

[code] // Echo everything in source that is greater than 5
int[] source = new[] { 3, 8, 4, 6, 1, 7, 9, 2, 4, 8 };
foreach (int i in source.Where(x => x > 5))
    Console.WriteLine(i);[/code]

Or more impressive stuff like writing a functional version of QuickSort:
[code]Func<intlist, intlist> Sort =
  xs =>
    xs.Case(
      () => xs,
      (head,tail) => (Sort(tail.Where(x => x < head)))
                             .Concat
                           (Single(head))
                             .Concat
                           (Sort(tail.Where(x => x >= head)))
    );[/code]
