java - error: cannot assign a value to final variable (int) -


ok i'm sure simple, i'm having issues , mind blank. =( know 'final' makes variable can't change that's pretty can figure out right now. , code...

if take out 'final' error comes "error: missing return statement }" first 2 methods.

edit: thank help, surprising how fast got help! took out 'final' , added 'void' first 2 methods. i'm sure it'll take time understand everything, helps.

there part 2 , here part have no clue on do... second part have test first program. supposed make separate file same code? if can great, if not thats fine i'll work on later.

you declare function 

  public static int removeonefromroom (int number)   {      totalnumber = totalnumber-number;   }

the emphasis here public static int, telling compiler function supposed return integer. not return in function body, compiler complains rightfully. either return something, or declare return value void.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
