java synchronized keyword needed on primitive getter / setter method? -

i working on piece of code , encountered : typedef jobject jthread; typedef jobject jthreadgroup; what significance of different typedef similar entry ? it allows have 2 different names same type. there (at least) 2 different reasons you'd want this: in code, want reader see type of data we're dealing with. after all, "thread" diffferent "group of threads", if underlying type representing them different. ability change type 1 of types without affecting other. if @ later stage, decide "jthreadgroup" better new type, can change without affecting "jthread". imagine have small game, count score in integer type. have count of players: typedef int scorecount; typedef int playercount; later on, decide need small number, short count players: typedef short playercount; same idea using "jobject", different base-type, possibly make easy understand.

javascript - Random Number, Math.floor(...) vs Math.ceil(...) -

i've seen lot of code random numbers generated like // random integers in interval [1, 10] math.floor(math.random()*10 + 1) anyway, feel i'm missing something. why don't people use more succint way math.ceil(math.random()*10); ? i tried test randomness , seems true far. in fact, subsequent code // generate random integers 1 4 var frequencies = [ 0, 0, 0, 0, 0 ]; // not using first place var randomnumber; ( var = 0; < 1*1000*1000; ++i ) { randomnumber = math.ceil(math.random()*4); frequencies[randomnumber]++; } ( var = 1; <= 4; ++i ) { console.log(i +": "+ frequencies[i]); } prints out 1: 250103 2: 250161 3: 250163 4: 249573 what missing? quick ot: there more succint way declare , initialize frequencies? mean frequencies[5] = { 0 }; c++... as stated in mdn reference math.random() returns floating-point, pseudo-random number in range [0, 1) is, 0 (inclusive) not including 1 (exclusive), can scale desired rang...
