java - How to check multiple variables at once? -

-

Is it possible to check all to write a block of code, or all the objects / variables of a particular type For a certain specialty? (Without having to enter a statement for each) - then set it to right or false things.


As you had 3 variables and ... 

  if (a = 0 || b = 0 || c = 0) {// Set any variable to minus 4}   
 The action described in the preform comment  
 
  
 Or, for a complex example, 4 arraylists of type integer:  
  from the list & lt; Integer & gt; Even new = ArrayList & LT; Integer & gt; (), // Positive also ints strange = new ArrayList & LT; Integer & gt; (), // positively weird ints negaodd = new ArrayList & lt; Integer & gt; () // Negatives also ints negaeven = new ArrayList & LT; Integer & gt; (); // Negative weird ints   
 Anything like that:  
  Whatever the test array is being if ("AnyArray" .isEmpty ()) {/ Tried = null; }   
 So it is that if any of the arrays are being emptied, then instead of [], they will return "null".   
 
 Hmmm, if you want to make something more interesting, then simply repetition the collection, it looks very functional to implement a filter and apply the map. Try Lamb's or Google Collections (see here for a good post). Here is an example using the vertical.  
  list & lt; Integer & gt; Strange number = filter (weird, asList (1, 2, 3, 4, 5));   
 For more potential ideas see here:  
  Disclaimer  Sometimes falling into the water with this kind of thing (when a Simple loop will suffice) obfuscates code over anything, so be careful.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
