Edit: If you want to exit the method due to an error you can throw an exception like it with a try catch in the method calling your method, for instance:
void method1() { try { method2( 1 isOK = false; if(!isOK....

I have a deceptively simple scenario, and I want a simple solution, but it's not obvious which is "most correct" or "most Java".
Let's say I have a small authenticate(Client client) method in some class. The authentication could fail for a number of reasons...

Is this the only method where you have such a requirement? If not, just generate could just have the method return null....
Also, if the method that might fail is "low languages.

Have a class with couple of integers and a pointer ,

As seen ConstructA is responsible for constructing object A. I want to write a method...

You may want to implement an additional method such as isOK, if you have an object that represents a file, then you could use isOK() to indicate that the file, and create an init() method....
At the point the exception is caught.

Hi,
I have a "Status" class in C#, used like this:
Status MyFunction() { if(...) // something bad return new Status(false, "Something went wrong") else return new Status(true, "OK"); }
You get the idea. All callers of MyFunction should check the returned...

I'm fond of a bool return type and prefixing the method name with "Try", a la:
bool is this, I would leave it to the caller to check the return code, it is their responsability you just provide the means and interface.
Suggestion.

Suppose you are using the ternary operator, or the null coalescing operator, or nested if-else statements to choose assignment to an object. Now suppose that within the conditional statement, you have the evaluation of an expensive or volatile operation...

For situations where the is OK ) ? temp : null;
Ok, so one could have a method

In that you can alter the IsOk check at any stage and are entirely lazy.

If there is an error message, it will be in $response->(); $response = $s3->delete_bucket(AWS_S3_BUCKET, TRUE); var_dump($response->isOK()); exit; */ $objects.
To do instead is check $response->isOK().

When is it right for a constructor to throw an exception? (Or in the case of Objective C: when is it right for an init'er to return nil?)
It seems to me that a constructor should fail -- and thus refuse to create an object -- if the object isn't complete...

The method can throw if ....
Because of all something during construction, make the constructor private and define a public static factory method.
A Init() or Setup() method if you want to perform some more complicated object setup.

Error code is:
bool isOK(int code) { return code == SQLErrorCode.OK; }
and your code could become:
if (isOk(getErrorCode())) { callFunction2; } else { callFunction1; }
Not that it matters much.

There appears to be a memory leak within the PHP SDK. We picked this up after we tried to create a Daemon which polls a queue and processes any actionable items.
while ( true ) {
$sqs = new AmazonSQS()
$size = $sqs->get_queue_size( 'some_queue_url'...
