In front of a long loop, it costs more (processor + memory) to assign redundantly the same value, or to check before the assignment?
int count = 0;
for(int i=0; i<100_000; i++){
if (...) {
count++
doLogic(count); // logic is strictly related with count
} else {
count = 0; //50.000 redundant assignment
}
}
VS.
int count = 0;
for(int i=0; i<10_000; i++){
if (...) {
count++
doLogic(count); // logic is strictly related with count
} else {
if(count > 0) { // 50.000 checks
count = 0;
}
}
}
And would it cost the same if count
would be present in a different object (injected as singleton
in a spring context) and the increments/check/reset would be like:
config.incrementCount();
config.getCount();
config.resetCount();
