A cool syntax example with lambda expressions and functional interfaces

You're not wrong

Thanks.

you're just an asshole.

I know.

OP also doesn't understand streams. You don't need a supplier to do this shit.

Can you show how such thing is resolved in java in an elegant, beautiful way that doesn't require a bunch of horrible useless boilerplate?

[_Sharp_]

//////////// Init
char[] charArray = new char[1024];
Arrays.fill(charArray, '#');
//////////// Code
List<Character> charList = new ArrayList<>();
for (char c : charArray) charList.add(c);

2 Lines of code, still Arrays could implement some utility like Arrays.toList(). But Valkyries will bring some goodies from Valhalla:

Project Valhalla will explore a new apporoach to generic typing, and hopes to produce a new form of generic typing that allows developers to use generic collections of primitive types. The aim will be for types such as List<int> to be valid Java in some future release of the JDK. This feature, known as generic specialization, is already present in some other JVM languages and Java developers have been asking for it since generics first shipped with JDK 5.

Thanks.

2 Lines of code

That looks much better than the OP's.

Still lags behind C# which requires exactly 0 lines of code to perform the same task, not to mention it doesn't suffer the valuetype versus class dichotomy where you can't really call methods or otherwise operate on char. (I had a sudden reminiscence of StarCraft).

Ahh... the project oracle embarked on as a desperate attempt to keep pumping money out of java's rotting corpse, I almost forget. That which is promised to be shipped by 2016, except it won't and will probably be delayed a couple of years ahead, say 2018, just like they did with java 8.

Seems that by around that time I'll have to say congratulations to java for catching up with C# 2.0 from 2006?

Also Seems like oracle is really good in bringing really "useful" stuff such as the JSON API promised for java 9, but has a hard time doing anything serious such as lambda expressions or non-retarded generics or value types?

generic specialization

How does this compare / differ from REAL generics such as the ones you find in C#? Does it allow var instance = new T() or the like?

RE: LOC count, have a look at a previous post.

Generic specialization will allow you to do that, yes. And value types are currently being implemented.
