this question extension of discussion found here . goal write 2 formatted columns of arrayed x , y data file (type double ). current attempt accomplish follows: try { fileoutputstream fos = new fileoutputstream("angle.txt"); dataoutputstream dos = new dataoutputstream(fos); (i = 0; < i_max-1; = + 1) { dos.writedouble(theta[i]); } dos.close(); } catch (ioexception error) { system.out.println("ioexception: " + error); } this code derived example found here (dataoutputstream). having limited grasp of java, expected work 1 column only; instead produced this: ?¹™™™™™š?¹™™™™™š?¹™™™™™š?¹™™™™™š?¹™™™™™š?¹™™™™™š?¹™™™™™š?¹™... i don't understand i'm doing wrong. any insights can offer great help. my next question be: how format not 1 two columns of type double , formatted ("%1$16.6f, %2$16.6f", time[i], theta[i]) . right i'm following this discussion. however, compiler dislikes approach use of writedouble . yo...

the classic way create constructor function like: var obj = function(param){ this.param = param; this.method = function(){ console.log(this.param); } } but why can't this: obj.anothermethod = function(){ //some code } (i know obj.prototype.anothermethod ). in practical usage can't understand why use string.prototype.func instead of string.func define new method. because string constructor function , it's impossible add method it? those different things. if add method constructor.prototype , available on instances of constructor . you can add methods constructor itself. however, instances won't inherit them. for example, charat method defined on string.prototype , can use both "abc".charat(1) , string.prototype.charat.call("abc", 1) . but fromcharcode defined on string , can use string.fromcharcode(65) , "abc".fromcharcode undefined.

after initializing singleton object via -[appdelegate didfinishlaunchingwithoptions?] , how 1 pass pointer of object view controller? it helps, let's assume object stand-alone reasonably coupled ui. (for example, managing server connection thread.) prefer more "intimate" signaling via nsnotificationcenter . it depends. if object needed single view controller, initialize in viewdidload . if is needed entire app, initialize in app delegate. in case, best in app delegate since needed lifetime of application , not used 1 view controller. you can create property in app delegate , put object in it. can delegate anywhere in application this: ((appdelegate *)[uiapplication sharedapplication].delegate) so, long have #imported appdelegate.h in file accessing app delegate from, can object this: myobject *object = ((appdelegate *)[uiapplication sharedapplication].delegate).propertyname;

is possible have spring oauth2 error messages localized? error messages invalidgrantexception , usernamenotfoundexception. maybe late, gonna leave answer here maybe else interested. as far know, there no builtin internationalization feature in spring oauth2 (please correct me if wrong). however, spring lets extends default implementations up. there 2 possible approaches i'd guess: 1. backend internationalize error messages on server , return them api. requires locale resolving (e.g. header locale resolving) 2. backend + frontend attach additional error codes response , frontend need map them localized message. the idea implement custom tokengranter , translate authenticationexception own exception (e.g. invalidgrantexception) on authenticating. example below creates different error codes different types of invalid_grant (appoache #2) : public class customtokengranter extends abstracttokengranter { private static final string error_code_key ...
