#16180 — Java Programming Best Practices

I have a dozen books on java, but no book specifically on best practices. What do you think. Will some thing short suffice.

Thank you,

     I like "Effective Java" by Josh Bloch.  This book is about
best practices down in the trenches: How to write good Java code
and what to avoid that would make it less good.  It's not much
concerned with best practices at the Big Picture level -- system
design, data integrity and security, etc. -- but an excellent
resource at the let's-write-some-code level.

It is not difficult to Google.

Of course Google would produce links without
referrals.

And yet, google would still somehow make money on the search. Perhaps 
its not a bad thing to link to a relevant page which also provides the 
linker with some financial incentive to link in the first place?

Of course. I think most people understand that Google is a business
and that they make money from ads.

I am not generally against people making money on being helpful.

If Roedy has been the first to suggest that book with the link
and the page had contained a note explaining that he would make
money if the reader clicked the link and bought the book then
I would certainly not have posted anything.

If just one of the these has been the case, then I would
probably not have posted either.

But trying to make money from usenet without really
providing any help and hiding that one is making money
is a tad too greedy in my book.

Absolutely /Effective Java/ is the #1 book for Java best practices.

/Java Concurrency in Practice/ is the goto book for practical concurrent 
programming in Java.

IBM's developerworks.com/java site is chock-full of best-practices articles.

Angelika Langer's site is the best to introduce generics.

Patricia Shanahan's has the best advice for beginners.

mindprod.com has the best overall advice about Java, minus a few glitches here 
and there but always well meant.

Know the Java Coding Conventions.

Please don't spread hate propaganda.

When any site makes statements, in its top paragraph no less, such as

"XYZ is the #1 source of evil on the planet today." against a group of people collectively, that is pretty much the definition of hatred, prejudice, and bigotry.

Pretty ironic and hypocritical, given that I'm guessing they would claim they are "fighting hatred and intolerance".


To the curious reader:
If you cannot agree with the above statement as-is, and have to check specifically what the "XYZ" above is, to say "Well, if it's (this) group, its okay, but if it's (that) group, well, that's just bigoted"...
that in itself would be hypocritical.

I said, "about Java", and I am not spreading hate propaganda here.

If "XYZ" is a racial, ethnic or gender distinction you're right. If "XYZ" is 
someone or group of someones excoriated for their choices, not their inherent 
being, you're wrong.

Bullcrap.

You fail to distinguish hate speech, which targets people based on their 
inherent characteristics, from criticism, which targets people based on their 
actions.

You don't get to simplistically sloganize morality and lock everyone else into 
your idiolectic definitions.

I stand by my claim that Roedy's site gives generally decent information about 
Java. Agree or disagree with his politics, but if you're going to accuse him 
of "hate propaganda", you'd better be ready to back that up with actual 
evidence, not vague handwaving and slander about political discourse with 
which you personally happen to disagree.

So you're saying it's wrong to be bigoted against people because of ethnicity or gender, but its perfectly fine for any other reason.
And words like " I would be interested in hearing your ideas about would could be done to help eliminate XYZ", and comparing that group of people, to a disease, is just fine.
Interesting.

Personally, my view is that if bigotry is wrong, then it's wrong for any and all reasons.
(In the same way that if someone is for "free speech", they should support speech they dont agree with... if someone is against bigotry, they should be uniformly against it, even when directed against groups they dont personally like)


Let's try this for size:

"Hindus are a crazy messed up people. They're like a disease. Let's do everything we can to eliminate Hinduism from the planet."

Whether or not you agree with the statement, do you think that is hate speech?

If you do, you're a hypocrite, since you said it wasnt when directed against a DIFFERENT group of people. If you dont think so... you might want to get a second opinion from someone outside your normal circle of acquaintances.

PS:

hate speech is hate speech, no matter whether it's directed at "inherent characteristics", or "I hate everyone whose first name starts with the letter Q"

Legal != moral. Legally,I can go stand up in a public square and rant about how much I hate people who have names starting with Q. Clearly, that's hate speech, even though there is no legal recognition of it.

But even from a legal standpoint, religion is a protected characteristic, so that site is clearly engaging in hate speech.

I did not say that.

You misquoted me.

I said nothing about whether it's right to be bigoted. Instead, thank you for 
disingenuously misstating my point, I said that it is not bigotry to castigate 
someone for their behavior.

You are engaging in begging the question and straw-man arguments.

Fine, if we were discussing someone's bigotry, which we aren't.

We're discussing Roedy's political statements, which are not bigoted.

I never said any such thing. You made that up out of whole cloth.

You are like Humpty Dumpty in _Through the Looking Glass_: "When I use a word, 
it means exactly what I choose it to mean, no more, no less."

But your definitions happen to be wrong.

Hate speech is hate speech, as you so circularly claim, but speech excoriating 
someone's actions is not hate speech.

You don't get to just make up your own definitions.

> Legal != moral. Legally,I can go stand up in a public square and rant about how much I hate people who have names starting with Q. Clearly, that's hate speech, even though there is no legal recognition of it.

Wonderful _non sequitur_, absolutely impressive in its irrelevancy.

> But even from a legal standpoint, religion is a protected characteristic, so that site is clearly engaging in hate speech.

Huh? Religion?

And religion is a matter of choice, so one is perfectly free to speak against 
the practices of any relgion, including even atheism.

Otherwise statements like, "That church stole gazillions from gullible poor 
people" would be hate speech, which it isn't, or "That other church engages in 
hate speech" would be hate speech, which it isn't.

You continue to slander Roedy's site with no basis.

You need to stop using incorrect definitions, and you definitely need to stop 
derailing Java conversations with your trollery.

Please, I ask politely, go back on topic or shut the frak up.

I think you are arguing from very different legal systems here.  If 
anything, Philip you should mention the legal basis you are arguing 
from.  The US, for example and as far as I know, are strictly liberal 
when it comes to freedom of speech.  In the US you are allowed to say 
things which are banned, for example, in Germany (for historic reasons).

I don't think Roedy's statements qualify as hate speech (and I come from 
Germany which has a more restrictive approach to freedom of speech). 
Whether you think those claims are true or not, or even good to have 
that on the site is a totally different question.

Cheers

Furthermore I recall that Roedy lives in Canada, and maintains his web 
presence there, complicating the whole "US law" thing even more.  (What 
treaties exist to cover speech?  I don't know.)

There's some blathering about freedom of speech in the UN Declaration of 
Human Rights, but it's vague on where freedom of speech stops. The 
Durham Conference produced a toothless document a few years ago, but 
considering that several notable countries boycotted, it's not really 
worth talking about.

The US has extremely liberal free speech laws--hate speech is actually 
protected free speech here; considering that, e.g., Arab countries have 
attempted to push for making defamation against (read: criticism of) 
religion not-free speech, it's very doubtful that any treaty the US 
would agree to would be tenable to the rest of the world.

     Here's something I know about R.G.: He favors vigilantism
and vandalism as a means of regulating the Internet.  See the
thread he started this past Valentine's Day titled "the Olson
Timezone Database," in which he writes (apparently in haste, but
he reaffirmed his position in follow-ups):

	"A hope Anonymous soon gets round to putting these
	unprintables out of business."

And the relevancy is?

The political parts of Roedy's web site seems at be very
negative towards entire groups without evaluating any
individual behavior.

The before mentioned parts of his web site does seem to fit the
definition of bigotry pretty well.

A very one sided and rather extreme point of view with a tendency
to ignore facts on certain topics.

Given that having a first name that starts with Q is
not an action of that person (unless he changed his
name himself), then I can not see that example
