> > Function Pointers -- Missing

> Java 8

Yet again, they admitted an important feature was missing. Again, I am not familiar with Java 8 but I suspect their implementation is horribly wrong.

> > Constructors can't call each other

See my response.

> > Methods With the Same Name as Constructors

> Yea that's allowed, I don't see what's wrong with that. It's a real function name so it should be allowed. I've never accidently made this error.

I have. I guess I have just logged more time in Java than others.

Please tell me how to do it properly. IE, if I have a variable of type Foo that is holding a value of type Bar, how do I invoke the function with Bar instead of Foo in the signature?

My point exactly.

Other languages just use globals. Because they are useful and people need them.

Java makes you invent a new programming paradigm to overcome its artificial limitations.

And what do you do when you blow out the 80-char limit on columns?

Oh let me guess. You like your 1024-char limit on columns because you are using a superior IDE.

> > No List Literals

I don't recall that being an option. I do know that people used to prefer the curly brace format but that turned out to cause memory leaks.

The issue with inner classes is that so many thing are contrary to expectations. I started to list them all but it got too long. I'll have to revisit it and try to condense it down.

The point is the reason why they do it is because it's easier to write, test and debug these other languages than Java. People know that coding in native Java is slow and cumbersome and time-consuming with no significant benefit.

> > Speaking of the JVM...

> I'd love some numbers on these claims.

What claims need numbers? LLVM and PyPy exist. JS with JIT kicks the pants off of almost everything --- because it is compiled down to native machine code. Go look them up for yourself.

JIT is the new fad, and it's a huge deal.

Name one.

> > Why Use Java at All?

> Why use any language at all? Write binary and opcodes (like I've been doing in my CPU project). It's very fun!

I write code to get the job done so I can get paid, my company's stock price can go up, and I can get money. It's a job. Yes, I love programming, but I prefer to get as much done with as little work as possible.

> In seriousness Java gets concurency right and I've not found another language that lets me write concurrent code like this ever before. Very nice platform to run on and one of the worlds best VMs. Everything is simple and documented well. I don't need to read a novel to get something working. I can think of a class, type that a control-space on my IDE, get a list of classes, find the one in the right package and move on. No google, no searching, just tooling and built in documentation. What's even better is most of the language is implemented in Java! I have the sources downloaded so CNTRL+Click and I can see everything's implementation! I'd love to see a python dev do that (I cant and I've been writing python for years).

Yeah, you strike me as someone who only knows Java. Let me know if I'm wrong.

> I'll be emailing the author at this email: jgardner @ XXX .net and giving him this comment. I hope he can rebute some of these points.

My email is jgardner@jonathangardner.net. It's been around for decades so feel free to send me as much email as you like. I'll see the good stuff and the spam folder will eat the rest.

Let me change your example:

class Test {
private final int i;
public Test(int i) {
this.i = i;
}
public Test() {
this.test(7);
this(10);
}

private void test(long number) {}
}

Tell me how that works out for you.
