what instruction takes more time between if() or variable initialization ? will more efficient first check whether given variable has non-zero value , set if nonzero? for example : boolean ! if (boolean) boolean = false; or directly : boolean = false; most faster not check. depend on type of object being set (in case, boolean, "simple set"). particularly special objects have "simple compare" , "complex set" benefit checking first. and if easy check , hard change, "set" function should check itself. an exception shared memory between processors there lot of contention, since writing memory force caches of other processors flushed, takes time.
