how can create method accept comparator wildcard argument, , capture class , use comparator ? public list<string> myfilter(comparator<?> comp, object value, class c){ return mylist.stream() .filter(s-> comp.compare(c.cast(s), c.cast(value))>=0 ).collect(tolist()); } edit: ok, in fact, andrew's answer interesting , works quite :) yet,given comments, should want is: instead of trying cast within method, expect cast had been done within comparator so give: public list<string> filter(comparator<string> comp){ return mylist.filter(s->comp.compare(s, null)>=0).collect(tolist()); } and when calling it, should like list<string> mynewlist= filter((string s1, string s2)->{ try{ int i=integer.parseint(s1); return integer.compare(i, myrealcomparevalue); }catch(exception e){ e.prin

i trying compare 2 arrays using jquery , remove duplicates that. this code.is logic correct? var list1 = [6, 7, 3, 4, 1, 2]; var list2 = [2, 4, 6, 5, 1, 9, 8, 7, 8]; var newarray = []; var index1, index2; $.each(list1, function(i, value)) { index1 = $.inarray(list1[i]); index2 = $.inarray(newarray[i]); if (index2 == -1) { newarray.push(list2[i]); } } expected output: [3,5,9,8] try this <script type="text/javascript"> var arr1=[6,7,3,4,1,2]; var arr2=[2,4,6,5,1,9,8,7,8]; $(document).ready(function(){ var newarray=$.merge($(arr1).not(arr2).get(),$(arr2).not(arr1).get()); console.log(newarray); }); </script> it give out put as [ 3, 5, 9, 8,8 ] another answer with using $.each,$.inarray , .push try var list1 = [6, 7, 3, 4, 1, 2]; var list2 = [2, 4, 6, 5, 1, 9, 8, 7, 8]; var newarray = []; $.each(list1, function(i, value){ if($.inarray(value,list2)==-1){ newarray.push(value); }

i'm little confused regarding ioc registration. assuming have visual studio project called 'project 1'. within project dependent , it's dependency. register dependency implementation within installer in project 1. now project 2 wants use dependent described in project 1. right in saying project 2 must same registration dependency inject dependent? i.e. isn't registration in project 1 pointless? the reason ask because under impression registration all done calling code, 'final consumer' of these implementations. i've seen installer files within 'project 1' equivalent in solution i'm looking at.

using ida pro analysing file, have run across code don't quite understand: mov eax, ss:dword_410cc5[ebp] ; call eax; indirect call near proc going address - 410cc5 - see this: ile.........clos ehandle......... i assumed in first code snippet in eax name of library function stored, called call eax; indirect call near proc but problem address 410cc5 not correspond name (see attachment). @ address zeroes. does anyway means @ call eax; indirect call near proc we call closehandle? if so, why isn't right address passed eax? when call instruction appears in disassembly, means routine/function called @ point. if routine has absolute address, instruction appear call 0xaabbccdd . if address of function being called dynamic address (this kind of addresses resolved when os loads executable), it's called via enregistered value. however, instruction used calling routine—that's all.

scala beginner trying store values obtains in scala foreach loop failing miserably. basic foreach loop looks currently: order.orderlist.foreach((x: orderref) => { val references = x.ref})) when run foreach loop execute twice , return reference each time. i'm trying capture reference value returns on each run (so 2 references in either list or array form can access these values later) i'm confused how go doing this... i attempted retrieve , store values array when ran, array list doesn't seem hold values. this attempt: val newarray = array(order.orderlist.foreach((x: orderref) => { val references = x.ref })) println(newarray) any advice appreciated. if there better way achieve this, please share. thanks use map instead of foreach order.orderlist.map((x: orderref) => {x.ref})) also val references = x.ref doesn't return anything. create new local variable , assign value it.

i've created app i'm printing text data app bluetooth printer. app working fine 1 thing there i've given harcoded name of bluetooth printer print data. i want make app send text data android compatible bluetooth printer. or small hint helpful. is there property of bluetoothdevice can helpful in finding out whether connected device bluetooth printer or not? in advance! if use bluetoothdevice class, can call getbluetoothclass() function. returns bluetoothclass object, , on can use getmajordeviceclass() major device class , getdeviceclass() minor device class. believe printers should have 1536 major class , 1664 minor device class. might want oduble check device classnumbers, though.

i want call function unloaded package having function name stored in list. normally use library(shiny) pagelist <- list("type" = "p") # object function name (will loaded .txt file) get(pagelist$type[1])("display text") but since when writing package you're not allowed load library i'd have use like get(shiny::pagelist$type[1])("display text") which doesn't work. there way call function function name stored in list, without having load library? note should possible call many different functions (all same package), using e.g. if (pagelist$type[1] == "p"){ shiny::p("display text") } would require quite long list of if else statemens. use getexportedvalue : getexportedvalue("shiny",pagelist$type[1])("display text") #<p>display text</p>
