i working on datasync service, i'm getting json response webserver. question how pass response activity i'm calling service. you can use eventbus , send data desired activity subscribing event. for eg: compile 'org.greenrobot:eventbus:3.0.0' eventbus class public class datasyn { public final list<yourmodel> yourmodel; public datasyn(list<yourmodel> yourmodel) { this.yourmodel = yourmodel; } } send data response : eventbus.getdefault().post(new datasyn(yourdatalist)); subscribe , receive data wherever need: @override public void onstart() { super.onstart(); eventbus.getdefault().register(this); } @override public void onstop() { eventbus.getdefault().unregister(this); super.onstop(); } @subscribe(threadmode = threadmode.main) public void ondatarecevied(datasyn event) { if (event.yourmodel != null) { populatedata(event.yourmodel); } } above easiest way share data

i have player object can throw exception inside constructor, in main function i'm creating 2 player objects inside try block. want store these 2 player s in std::array that: try { player p1(10, 10, ikazuchi); player p2(70, 10, hibiki); std::array<player, 2> players = {p1, p2}; } the problem wouldn't able use array outside of try block, , heard placing main code inside try block bad idea. i can't declare std::array after try block because p1 , p2 no longer exist there. i can solve problem std::vector , have read better use std::array when know size of array during compilation. i create default constructor create objects fill them inside try block, seems more proper create in constructor. what best practice that? you can around issues using dynamic allocation or boost::optional<std::array<player, 2>> , real question is: should you? is, assume 1 of player objects fails construct , throws exception. players array after t...

i want xor number k n time. easiest way xor n time in loop. there better way? int t = k; for(int = 0; < n; i++) k = k ^ t; xoring n copies of k produces k if n odd , 0 if n even. k ^ k == 0, 0 ^ k == k, , alternates between results every additional k. (your code xoring n+1 copies of k together, i'm guessing mistake.) int result = (n % 2 == 1) ? k : 0;
