Closures in Java 7
Published (2009-11-27 05:50:00)
I wasn't aiming that at anyone. It's my default opinion: we fear change. In practice I've generally been pleasantly surprised.

Reading from a file

Closures in Java 7

darted wrote: Agreed. This is why I am ambivalent about closures. I don't see an overriding need from my personal experience, but if added will at least try them. I might like them ;) What I see is a way to be able to avoid lots of "boiler plate" code. E.g why do we have anonymous classes, and when do we use them? Why can't that be expressed in another way?

I'm doing the exact same thing in my GUI... the only difference is: There's a JFrame with a JButton that adds a Runnable 'maze-solver' to a cachedthreadpool. Is that wrong? It's not going to be your code using up all that memory, it's going to be the data...

How do I create a isEmpty()...
Published (2009-11-25 18:31:00)
You can. Note that if head is null then tail should also be null, and vice versa. So checking both is a data integrity check more than an empty check. Get it?

Jar Indexing problem (advanced)
Published (2009-11-25 21:07:00)
Are you trying to work with jars within jars? If so then this is not at all easy since there is no built-in method for doing this.

Even given the fact that objects take up some room (and a [][] is an array of arrays), and a Java byte might take up more space than it should, and there's probably some overhead for Java's own memory-management, I can't even get to 2Gb, let alone 3. But I'm not...

Sure. They are common.

Don't. They are irritating.

So they've once again fallen for the Me2! crowd and decided on adding something for no other reason than that Ruby has it and someone claimed that "Java iz ded" if it doesn't get it.
Good thing I'm ever more specialising in pl/sql and bpel, means I'll probably not have to maintain the rubbish that's certain to be churned out by n00bs and academics thinking it's all a great idea.

It is garbage collected. Store a reference to your remote object in a static variable.

I also need to send this number to a piece of hardware in a hex code format.
BigInteger.toString(int radix)
...the number will most likely be much larger than 257 and can end up larger than even BigInt can handle.
There is no BigInt type in core Java. If you're referring to BigInteger, I'd be curious as to the size of number you're expecting to handle. Please describe an actual ...

Example: If i fire "java myProcessInfo <processName>" as a command,
then be this command run on any OS it should give me all the details of the process which i am looking for.
Obtaining process information is inherently OS-dependent, even under the same OS family like Unices.
(This theoretically does not preclude having a nice Java wrapper, which I am however not aware of.)

Define "good".
2) What happens if the sum of the two integers EXCEED the maximum allowed integer width?
It will simply wrap around to Integer.MIN_VALUE

For a start, let's try to clarrify what you're trying to do... and why ?
You want to import my.package.* at runtime, right?
It's possible, but what's your current Java skill level? Would you call yourself a beginner, or intermediate? I only ask because this involves the reflections API, which is generally regarded as an "advanced topic", to be kept on the top shelf, out of reach of ...
