possible duplicate: objective-c java cross compiler i have working iphone app , want convert android app minimal effort. can suggest ? i don't think so. you're best bet have been develop application scratch using platform appcelerator or phone gap . the commenter makes excellent point: platforms fundamentally different. straight conversion of code won't work. have convert framework/api calls , restructure of ui. not framework different, assumptions made platform totally different well. possibly best way reuse code (this isn't easiest, keep in mind) convert objective c code c or c++ , make use of android ndk. won't able reuse of ui code, might able reuse significant amount of application logic depending on application does.

i have midterm coming next week , going on sml notes provided in class. came across currying example , not sure how worked. it simple function computes power of number. here function definition: fun pow 0 n = 1 | pow k n = n*pow(k-1)n i'm not sure how function works when pass following arguments: val x = pow 2 2 this way see it: =2*pow(1)2 =2*(2*pow(0)2)2 =2*(2*(1)2)2) the result should getting 4 don't see how result steps have carried out above. help please. thank-you. ah, standard ml of new jersey, how miss thee... anyway, let me go through step step. remember currying, unlike dinner in front of me (which incidentally curry dish), way of dealing 1 argument @ time return new function. in mind, apply first 2 given function. since 1 pattern matches, have new function -- let's call "curry": curry n = n * pow 1 n note have "inner" version of pow function address. doing so, again, 1 pattern matches. let's call inn...

(unless of course value of $x false-y.) let's analyze this: assuming $x equal '400' : ($x == ('100'||'200'||'300')) // ^ ...

this has been bugging me while , have yet find acceptable answer. assuming class either subclass or implements interface why use parent class or interface type i.e. list list = new arraylist(); vehicle car = new car(); in terms of arraylist gives me access list methods. if have method takes list parameter can pass either list or arraylist arraylist list. within method can use list methods can't see reason declare it's type list. far can see restricts me methods i'm allow use elsewhere in code. a scenario list list = new arraylist() better arraylist list = new arraylist() appreciated. using interface or parent type recommended if need functionality of parent type . idea explicitly document don't care implementation, making easier swap out concrete class different 1 later. a example java collection classes: if use list , set etc. instead of e.g. arraylist , can later switch arraylist linkedlist if find gives e.g. better performance. that, chan...

both exist example here: map.empty[int, int] map(1 -> 41).empty set().empty set.empty but here class methods existing: list.empty //ok list(1,2,3).empty //doesn't exist array.empty //ok array("a").empty //doesn't exist isn't empty perfect case class method (and shouldn't instance method empty deprecated therefore)? or should empty instance method added classes missing it? is there language point of view makes difficult having empty class method (e. g. type inference, higher-kinded types, ...). ps: suggested maps default values harder achieve without instance method empty : map[int, int](1->2, 21->42).withdefault(_*2).empty what think? that's true, empty method on class instance. reason why it's required sets , maps because implement builders using method. guess reason why wasn't included elsewhere because wasn't typical use case.

how replace 2 double quotes single 1 using jquery? for example: need replace sam @ ""home"" to sam @ "home" looking similar regex (which replaces double quotes single quotes): mystring.replace(/"/g, "'") try this: mystring = mystring.replace(/""/g, '"'); the regex captures 2 double quotes , replaces them one. we're using regex replace more single match (javascript's replace replace first one). note second argument replace string. represent " in string need escape it: "\"" , or use single quote string: '"' . javascript supports both.

for moving individual 1 branch realize there few options in git. have experimented git merge , git cherry-pick failing see when git cherry-pick preferable. my understanding following: git merge <hash> moves specified commit 1 branch other preserving 1 commit. git cherry-pick <hash> creates copy of commit in second branch separate own commit hash. the first option seems preferable me instances when cherry-pick preferred? say have branch master has bunch of commits. maybe made change appropriate on master , don't want bring in all of changes (a small bug fix, example, or addition of small feature). git cherry-pick , can grab only commit other branch , bring master .

multiple objects in our database need tagged string tags (completely arbitrary). 1 solution classic many-to-many relationship representation: table customer customerid, customername table product productid, productname table tags tagid, tagname table customertags customerid, tagid table producttags productid, tagid another solution have xml column represents tags path secondary xml index improve sequential lookup: table customer customerid, customername, tags table product productid, productname, tags where tags xml column have tags <tags><tag name="tag1" /></tags> , path index /tags/tag the first solution gives faster lookup, adds more tables. second solution slower cleaner. i'm new sql , might have overlooked something, input highly appreciated. my vote on first solution. first of all, xml slower process on sql server 2008 equivalent straight tbl-bridge-tag setup. if wanted find products tagge...

since learned rdbms, started thinking in relational model , less in object oriented. i'm having trouble trying store , query data in java data structures. i want write application has entity sets relate each other made each entity own class. attributes each entity instance variables. okay think we're far. title , game entities. game isa title title should parent class , game should inherit title (think of game physical copy , title name of game). i have set of games in main class , can iterate through if want find specific game. how find specific title? don't have set of titles because title inherited assume should iterate through games , when find name of title, add set unique titles back. game mutable (isbought can change) using set bad idea? best way create entity sets in java? using map instead of set map id object? fixing object-relational gap not easy task. there orm (object-relational mapping) frameworks that. have learning curve. hibernate ...
