Why Java sucks

[Prince Pwn]

Java is very CPU heavy. It's also very slow. Java is a fun language to use but both Java as a whole and Sun Microsystems the company and their Java fail when it comes to speed.

[DemonWasp]

This is an old, tired argument, but here we go again: Java isn't slow. Go build a benchmark that uses equivalent code between Java and (supposedly faster language). Chances are good that Java's performance will be within about 5% of the reference implementation.

If it isn't, go get a JVM that's at least version 5 (1.5) or 6 (1.6). SUN's versioning system is dumb as anything, but that's a separate issue.

If it still isn't, please post code. Try not to make the usual "Java versus C benchmark" mistakes, like accidentally using synchronized collections, non-buffered or synchronized (or both) I/O, concatenating too many strings, etc.

If anything, Java is more guilty of being memory-heavy (30-60mb overhead, depending on launch configuration) than CPU-heavy. Even this is a minor issue, except at launch-time where the JVM has to be loaded before your program even starts to load.

Java works great, countless companies big and small use it for everything from desktop to enterprise. It scales well on the enterprise side of things. This argument is definitely moot.

Like any development platform that uses a virtual machine, there are trade-offs. But they are largely negated since Java bytecode is compiled by the JIT compiler, into a lower level machine format.

Java has been owned by Oracle since acquiring Sun in 2009.

Java is plain dirt. C++ over java any day. But +1 for anyone who said python. If you're a very good programmer it is redundant to use a language that "nannies" you. Development speed for the win.

Back to original post has java adopted any of those features it didn't have almost 6 years ago

[Tony]

Well the last major release was Java 6 and that happened in December 2006. So that's a no for most (all?) points, but it hasn't really been six years either. Lets see what's in Java 7's branch.

Java 7 has been released for preview. See here: http://jdk7.java.net/preview/

I heard a rumour recently that apple was going to stop supporting java on their machines, like they decided to not support flash. I was wondering if this is true or not.

Edit: Also I read something about success of competitions based on language, very interesting, C programs ran out of time and memory the least, C++ next, and Java and python last, but it really didnt make a difference, the biggest difference was in failure to compile, which is a reflection not upon the language, but rather on the fact that n00bs are more likely to get into java than C++ and especially compared to C. It was actually a very very interesting chart, and if anyone wants I can post the chart.

They still support Flash, they do not ship it pre-installed due to a serious loss of battery life: http://www.engadget.com/2010/10/22/apple-responds-on-missing-flash-in-new-macbook-airs-says-get-us/

Yes please...

I meant like on iPod touch and iPad, where applications aren't even allowed to have it, like web browsers can't be made which support flash on ipod touch. (However cloud browse will decrypt flash and convert it at a server so that you can actually use it, its the most amazing app ever)

So will SkyFire...
There is a Cydia flash available...but I don't think that counts...

mirhagk, please post the chart. It seems to be very interesting.

By the way, I am starting to learn the basics of Java and it doesn't seem that bad, but yet again, I'm still on the basics

Thanks!

So you mean pascal, not python.
