i'm writing monte carlo simulation in java involves generating lot of random integers. thinking native code faster random number generation, should write code in c++ , return output via jni. when wrote same method in c++, takes longer execute java version. here code samples: random rand = new random(); int threshold = 5; int[] composition = {10, 10, 10, 10, 10}; (int j = 0; j < 100000000; j++) { rand.setseed(system.nanotime()); double sum = 0; (int = 0; < composition[0]; i++) sum += carbon(rand); (int = 0; < composition[1]; i++) sum += hydrogen(rand); (int = 0; < composition[2]; i++) sum += nitrogen(rand); (int = 0; < composition[3]; i++) sum += oxygen(rand); (int = 0; < composition[4]; i++) sum += sulfur(rand); if (sum < threshold) {}//execute code else {}//execute other code } and equivalent code in c++: int threshold = 5; int composition [5] = {10, 10, 10, 10, 10}; (int = 0; < 100000000; i++) { srand(time(...

i've started developing android apps , wondering way better in case of adding fragments activity. let's assume view activity contain 3 fragments. won't changed. same. better add them tags or include them in activity code? and second question issue: let's have activity fragment list. when clicked on item want show new view. can replace list fragment new different fragment? if answer yes better creating new activity? thanks replies which way better in case of adding fragments activity one approach not 'better' other - both serve own purposes, static vs. dynamic comparison. for example, fragments declared in layout cannot given arguments using setarguments() . such fragment can not replaced fragment: if it's part of layout, it'll there. of course can still show/hide instance, attempting remove through fragmenttransaction not work. static elements easier work though, because have well-defined lifetime , behaviour. regarding seco...
