I've got a scheduled task which runs on the minute, I've also got a couple of Date fields that are set to different times. When the task runs, I want to check if the time it's running is equal to any of my predefined set Date fields. What's the best way to approach this? |
[12:42]
|
| bojangles |
(n.b. I can't schedule the task on a cron expression to run on those dates, it needs to poll on the minute) |

if (LocalDate.now().isEqual(markedTime)) { ... yup we're on the date ... } |
[12:46]

| bojangles |
surial, can I check it to the minute? and disregard seconds? |
[12:46]
|
| surial |
bojangles: ah, so we're presumably talking Instant then. |
[12:47]
|
| surial |
Instant.now().truncatedTo(ChronoUnit.MINUTE).isEqual(targetInstant /* you should probably truncate this as you create it */) |
[12:48]
|
| surial |
If the marked 'run NOW!' thing is based off of reading human time, you should probably use ZonedDateTime or LocalDateTime depending on what you read. |

(1) you dont necessarily need to know the servlet api. |

pi0, a few things: your loop condition should be n > 0, not n >= 0, at least that's how I understand "Enter number greater than zero" |
[04:54]
|
| pi0 |
ah it is suppose to be greater than or equal to zero |
[04:55]
|
| bobek |
and the negative branch should point back to start, otherwise it's like being stuck there forever |

Logging is the recording of various events that happen in an application. Java has built-in logging, but use it right after gnawing off your own neck. Instead, consider ~slf4j, ~logback, ~commons-logging, and ~log4j. Also: see http://www.masterzen.fr/2013/01/13/the-10-commandments-of-logging/ |

i've got an assumption which i'd ask you to confirm/disprove: when doing something like "boolean c = getA() && getB();", is it correct that first getA() is called and if that returns "false", the && can no longer become true, resulting in getB() not being called? |
[06:28]

&& and || are short-circuit, so yes |
[06:29]
|
| logithack_ |
Maldivia: very good, thanks! |

logithack_: c = getA() && getB(); esentially translates into: if (getA()) { c = getB(); } else { c = false; } |

yeah, seems evident now. thanks for the term "short-circuit", immediately found what i needed :) |

I'm starting to think I might be doing things to generic here. I have three classes that inherit from Employee, so getAllEmployees will be returning a list containing lists for each type. |

Another design error there though. I have a getEmployeeById, and it returns the interface, Employee. Wondering how I would be able to make this more precise. I can't assume what ever is calling knows exactly the class of the employee with that ID |
[07:13]
|
| adadelta|txter |
I guess I could add getEmployeeType to the employee interface, which each class inheriting from Employee could set using the EmployeeType enum. Could ues that to cast to the right class after fetching a generic Employee from getEmployeeById, but it seems messy |

mohsen_1: the modern modern way to do it, is to use client javascript to upload straight into local doc store, and from there ajax it to your server. |
[11:44]

This makes it muuuch simpler to for example have progressbars, resume after network interruptions, yadayada. |

Though I do believe there are some practical limits about how large the offered file can be; with straight multipart <input type="file"> style it's basically limitless. |

The 'right' way to do it, is to have libraries for each targeted language. It's still nice to have the core REST api be sensible, but, hey, it's REST. Opinions differ. If you really wanna make this 'do it right' shit and take it seriously, don't ask here, go google for famous APIs and see how they do it. |

json is short for JavaScript Object Notation. It's a lightweight data-interchange format, based on a subset of javascript and very popular for webapps. See http://www.json.org/ for an explanation of the format. See 'json parsing' for more info |
[01:10]

json parsing |
[01:10]

JSON parsing can be done with Jackson ( https://github.com/FasterXML/jackson ). Do not use org.json; it sucks. You can ask me about exotic options that aren't recommended via ~exotic json parsing. |

json was added by: soulcutter on 10 Apr 2016 at 08:17 and has a literal value of: <reply>json is short for JavaScript Object Notation. It's a lightweight data-interchange format, based on a subset of javascript and very popular for webapps. See http://www.json.org/ for an explanation of the format. See 'json parsing' for more info |

What's the point of enqueueing soft&weak references if they're gonna be gc'ed anyway? |
[01:45]
|
| DranikProgrammer |
I just opened some old project of mine and flushed my mind why I am dropping them every time manually |
[01:46]

enqueueing? |
[01:46]
|
| DranikProgrammer |
Yep Reference::enqueue |

|
| DranikProgrammer |
Ahh... looking at old code is great |
[01:47]
|
| yawkat shrugs |
[01:47]
|
| yawkat |
when are you enqueueing them? |
[01:48]
|
| yawkat |
it can help with doing some atomic stuff |
[01:48]
|
| DranikProgrammer |
I have an abstraction layer over them, which adds strong and null reference. Each time I want to set a new value, I enqueue the reference, nullify the pointer to the reference, and create a new one |
[01:50]
|
| DranikProgrammer |
The only thing I want to know if calling Reference::enqueue is pointless |

Got it, the enqueue does not instantly delete the object underneath, so the reference queue can actually pick up the object |

Hi, if we want to get sorted set, which should we use? |
[01:52]
|
| saltlake |
Set or something else |
[01:52]

No, use TreeSet |

TreeSet is an implementation of SortedSet |
[01:59]
|
| DranikProgrammer |
Which is just an interface on it's own |
[01:59]
|
| saltlake |
Do I have to use TreeSet with SortedSet? |
[01:59]
|
| saltlake |
cheeser: ^ |
[01:59]
|
| cheeser |
Set<Integer> set = new TreeSet<>(); |
[02:01]
|
| cheeser |
"will it be sorted?" write a test and see. or read the docs. |
[02:01]
|
| saltlake |
cheeser: Then why did you give me the link of SortedSet? Or why did you suggest to use SortedSet? |
[02:03]
|
| yawkat |
DranikProgrammer: it's useful if you want to trigger your refqueue |
[02:03]
|
| cheeser |
because if you'll look at the "known subclasses" you'll see some options to us. also, i assumed you know how polymorphism, interfaces, and java work. |
[02:03]
|
| yawkat |
DranikProgrammer: for example for closing a resource |

interfaces |
[02:05]
|
| cheeser |
saltlake, interfaces is http://download.oracle.com/javase/tutorial/java/concepts/interface.html |
[02:05]
|
| cheeser |
"work with TreeSet" makes little actual sense |
[02:05]
|
| cheeser |
a TreeSet is a SortedSet is a Set |
[02:06]
|
| cheeser |
this is basic inheritance and polymorphism |
[02:06]
|
| saltlake |
So TreeSet has to be used in both case, it is the trick |
[02:08]
|
| cheeser |
there is no "trick." |
[02:08]
|
| cheeser |
this is how things work. there's no magic or subtlety involved. |

I have an interface Logger with implementations On and Off. Method is void log(Supplier<String> message). In On, it is calling get() and doing additional stuff, and Off has an empty method body. That's because the call is (in nearly 100 % of cases) computation expensive. Is that a good design, or is there better? |

Hi -- I've generated several JAXB classes and several of them have @XmlAttributes of isAdded, isUpdated, isDeleted. Can I use a generic method to take a list of one of these classes and return the item that has isIsAdded() == True? |
[03:23]
|
| asix3 |
I tried something like private <T> T getLatest (List<T> changes) {}, but I can't call T.isIsAdded() |
