Java may not be dying, but it does take off early on Fridays for golf. Java is not dying the same way Cobol was not dying 10 years ago.

I'm fairly certain Java and C++ have comparable speeds, and I think in someways Java's faster.

The lack of non-heap objects makes you bend backwards more than you should though.

Can you please provide real benchmarks?

I'm surprised nobody has mentioned Android yet. When you add in the Android factor, Java is probably still one of the most widely used programming languages today.

It's funny the article straight away brings up the verbosity argument as well. You want to talk about verbosity - take a look at Objective-C and Cocoa (again, hugely popular today!)!

Personally, I quite like Java.

Java is not as fast or faster than C(++). The assertion always makes me cringe. I won't say Java is slow(though the startup time is annoying for some tasks), as it does perform better than many languages. But how does it make sense to you that a platform written in C can produce results faster than C is capable of?

I primarily use java in my day job, and although there's a lot not to like about it, some standard complaints are somewhat overblown. For example, nothing really forces you to use long variable/method names, but even if you do, a modern IDE -- I use IntelliJ -- with auto-completion makes these fairly painless.

You can shorten it even further to typing 'fori' then triggering the expansion by pressing tab.

Best shortcut that every IntelliJ user should know is "Find Action" (ctrl + shift + a on Win), press and start typing what you want to do. Will even present shortcuts in the list for next time.

Java is doing just fine and with the addition of closures in Java 8 I expect the already incredibly rich set of libraries to improve dramatically.

There are some pretty awesome libraries already... check out https://github.com/jnape/Dynamic-Collections

Back in college when I was interviewing for jobs sometimes interviewers would first ask you to write any executing Java class because some interviewees said they 'knew' Java and couldn't do even that simple task.

A couple years later when Eclipse came out I told a coworker this anecdote and he joked that it was 'main' + ctrl-spacebar followed by 'sysout' + ctrl-spacebar. I lol'd.

Scala is a "scripting language?"

Also,

>When the JVM implementation of Ruby, JRuby, added native support for this instruction, its performance zoomed past the C-based Ruby VM, which for years has been the Ruby reference platform. As JRuby's performance continues to pull ahead, I fully expect it to become the reference implementation. Certainly, it will become the vehicle by which most organization first try out Ruby.

This was true at some time, afaik the MRI Ruby on 1.9.3+ is faster-than or about-the-same-as the equivalent JRuby implementation. I also know zero people who were first exposed to Ruby via JRuby.

JRuby is awesome btw. I just think this article has a bit of a defensive tone...

There's a lot wrong with Java, but even while having moved on and learned / used professionally many other languages I keep coming back to it and its ecosystem. There is still not another language / platform that provides the same level of a variety of things that are important to me: * platform independence * performance * low level features * simplicity and clarity (for reading, writing not so much) * infrastructur…

You can get all of that and clearer writing in c#, with Intellisense.
